Nano-revolution in drugs delivery

Nano-medicine - using nano-sized particles to deliver drugs - has the potential to revolutionise the treatment of common maternal and fetal conditions, without side effects or risks to the mother or baby, according to a leading researcher.

Jeff Keelan, principal research fellow in the University of WA's School of Women's and Infants' Health, said nano-technology had the potential to create drugs that "boldly go where no drug has gone before".

"In conventional medicine you take a pill, aspirin say, and it gets dissolved in the stomach, enters the bloodstream and circulates around the body so all of the organs and tissues in your body get exposed to that drug," he said. "It is very non-selective."

Nano-medicine is a bit like adding a postcode to medications - it allows the drugs to be targeted to a specific destination in the body.

Nano-particles, which are the "envelopes" that contain the drugs, are usually made out of a biodegradable polymer and are about the size of a virus, ranging from one to 200 nanometres in diameter. A nanometre is one billionth of a metre.

The "envelope" or shell has a chemical structure that enables it to be targeted to a specific tissue. Once the envelope has reached and entered the target cell, it dissolves and the drug is released.

"Because it goes directly to the cell of interest, the dose you need to give of the drug is much, much smaller, maybe hundreds of times smaller," Professor Keelan said. The average dose of a drug is 10 to 1000mg whereas for nano-drugs the doses would typically be 0.1-10mg.

Professor Keelan is working on nano-particles for pregnancy with three different targets in mind - the mother, the placenta and the baby.

"Sometimes women in pregnancy have to take drugs that might be harmful to the baby," he said. These include drugs for epilepsy, cancer, hypertension and depression. So if you can figure out a way of designing a drug that does not cross the placenta, then you know that the drug is just going to act on the mother without affecting the baby," he said. "I call them 'fetal-friendly' drugs."

It might also be possible to devise therapies that targeted the fetus only; for example, if a test during pregnancy showed that the fetus had a genetic or metabolic defect, gene therapy could be delivered directly to the fetus using nano-delivery. Cystic fibrosis was an example of a genetic disorder that potentially could be treated with nano-medicine.

Genia Technologies Collaborates with Professors Jingyue Ju at Columbia and George Church at Harvard to Develop a …

MOUNTAIN VIEW, Calif., Oct. 3, 2012 /PRNewswire/ -- Genia Technologies, Inc. today announced a collaboration with investigators at Columbia University and Harvard University to develop a nanopore-based sequencing system that will accelerate the use of DNA sequencing in the clinic. The three-way collaboration focuses on the development of a single molecule sequencing system combining Genia's standard complementary metal-oxide semiconductor (CMOS) integrated circuit, Professor George Church's novel protein constructs with Columbia's unique Tag-based sequencing chemistry approach. Genia has recently entered into an exclusive license agreement with Columbia University for use of its Tag-based sequencing technology. By combining standard protein nanopores with the tag sequencing chemistry (NanoTag) and semiconductor technology, the Genia chip will be more accurate, faster, and affordable than current commercially available technologies. This integrated circuit platform is designed for decentralized deployment, ease of use, and less upfront sample preparation, at a size and price ideal for diagnostics in the clinical setting.

"We believe DNA sequencing will dominate molecular diagnostics in the future," said Stefan Roever, CEO of Genia. "We have been working to fully operationalize a nanopore-based sequencing approach, and this chemistry will be the catalyst that helps us finally bring affordable, easy-to-use genomic diagnostics into everyday medical care."

"The Genia platform combines the single molecule detection capabilities seen in nanopore-based platforms with true semiconductor scalability," Roever continued. "We are thrilled to collaborate with Professor Jingyue Ju, Professor George Church, and their teams to develop the NanoTag sequencing chemistry on our platform and believe this Tag-based approach overcomes the inherent accuracy issues you have with trying to pull native DNA through the pore. We believe this will be the winning chemistry for nanopore-based sequencing."

This transformational platform, based on the innovative electronic Nano-SBS system developed by Dr. Ju and his team at Columbia's Engineering School in an academic collaboration with Dr. John Kasianowicz and his group at the National Institute of Standards and Technology, uses a robust sequencing-by-synthesis approach to determine DNA sequences electronically at the single molecule level, without requiring amplification or optical detection. The technology identifies DNA sequences not by detecting the nucleotides themselves with the nanopore, but by measuring the current changes caused by the passage of each of four different tags that are released from the incorporated nucleotide during the polymerase reaction. On September 21, 2012, Dr. Ju, Dr. Kasianowicz, and their groups published an article in the peer-reviewed journal, Scientific Reports (Nature Publication group), "PEG-Labeled Nucleotides and Nanopore Detection for Single Molecule DNA Sequencing by Synthesis" (2, 684;DOI:10.1038/srep00684), that successfully demonstrates proof of principle of the Nano-SBS system.

"We are very fortunate to have partnered with Genia Technologies. We are very impressed with their chip capabilities and are excited to work with them and take our novel tag sequencing chemistry to commercialization. Our published research with Dr. Kasianowicz represents the first step in further development of this novel sequencing technology. By scaling with a nanopore integrated circuit, the commercial implications and the impact on biomedical research and clinical diagnostics are very exciting," said Dr. Ju, Professor of Chemical Engineering and Pharmacology at Columbia University.

Genia's technology combines a nanopore array integrated on a standard CMOS chip. Software on the chip controls the insertion of the nanopores into the lipid bilayers and allows for active control of individual sensors on the array. Genia has strong IP around their analog electronic circuitry, which at the heart, controls each sensor of the array and allows for operationalizing the overall nanopore-based platform. In addition, Genia's patented protein construct and methodology solve the diffusion, capture rate, and translocation speed issues faced by alternative exonuclease-based approaches.

To make NanoTag sequencing a reality, a fusion protein is needed to position the polymerase near the nanopore's vestibule, so that the tags can be easily captured and detected in the barrel of the pore. As part of the Genia collaboration, George Church and his group will provide the protein constructs which are integral to the overall Tag-based approach.

"DNA sequencing is the future of molecular diagnostics and finding a platform that can be deployed straight into the clinic and enable rapid, easy to interpret results will be the way to truly achieve personal genomes worthy of precision medicine," said George Church, Professor of Genetics, at Harvard University. "The Genia integrated circuit combined with the NanoTag sequencing chemistry, seems to have a winning formula that makes it ideal for clinical care and may be the platform that finally moves DNA sequencing into the doctor's office to ensure earlier diagnostics, treatment, and better patient outcomes.

The first version of Genia's CMOS chip is in-house and is currently being used to further develop and test the NanoTag sequencing chemistry. The company expects to ship its first devices to customers for beta testing by the end of 2013 and expects to have a commercial product, on the market in 2014.

A step towards the future

Sri Lanka as a leading nanotechnology destination:

By Shirajiv SIRIMANE

Sri Lanka had been talking of introducing nanotechnology for almost 15 years; ministers had promised to build nano parks and provide other benefits to get such projects off the ground. However, very little attention had been paid to the matter.

A model of the Nanotechnology Centre in Homagama

Last Thursday, the much talked about and long overdue foundation stone for the 54-acre nanotechnology Centre of Excellence (NCE) was finally laid on Government land at Homagama.

Chairman Sri Lanka Institute of Nanotechnology (SLINTEC), Mahesh Amalean said the investment for the initial stage of the project is Rs 830 million. The nanotechnology park, funded by the Government and a few private sector entities, would enable companies to invest and develop their research centres incubation facilities and pilot plants in the environment of an advanced technology park.

This would help Sri Lanka to be positioned as a leading destination for nanotechnology, taking the country closer towards becoming the Wonder of Asia.

The second phase of the park will focus on the expansion of research and business development for the public and private sector in Sri Lanka and potential foreign direct investment from multinational corporations as well as SMEs through attractive incentives, terms and conditions.

One of Asias leading nano-scientists Dr Lalin Samaranayake told the Sunday Observer that Sri Lanka is sitting on a nanotechnology goldmine. It has not used its potential in the world market, he said

He said while Sri Lanka has the technology to reap economic benefits from nanotechnology in the island itself, the country only exports raw materials, giving all the benefits to the world. Sri Lanka sells nano raw materials such as graphite, silica, titanium dioxide and clay for various industries in the world and imports the finished products spending a lot of foreign currency.

A step toward minute factories that produce medicine inside the body

Public release date: 27-Jun-2012 [ | E-mail | Share ]

Contact: Michael Bernstein m_bernstein@acs.org 202-872-6042 American Chemical Society

Scientists are reporting an advance toward treating disease with minute capsules containing not drugs but the DNA and other biological machinery for making the drug. In an article in ACS' journal Nano Letters, they describe engineering micro- and nano-sized capsules that contain the genetically coded instructions, plus the read-out gear and assembly line for protein synthesis that can be switched on with an external signal.

Daniel Anderson and colleagues explain that development of nanoscale production units for protein-based drugs in the human body may provide a new approach for treating disease. These production units could be turned on when needed, producing medicines that cannot be taken orally or are toxic and would harm other parts of the body. Until now, researchers have only done this with live bacteria that were designed to make proteins at disease sites. But unlike bacterial systems, artificial ones are modular, and it is easier to modify them. That's why Anderson's group developed an artificial, remotely activated nanoparticle system containing DNA and the other "parts" necessary to make proteins, which are the workhorses of the human cell and are often used as drugs.

They describe the nanoscale production units, which are tiny spheres encapsulating protein-making machinery like that found in living cells. The resulting nanoparticles produced active proteins on demand when the researchers shined a laser light on them. The nanoparticles even worked when they were injected into mice, which are stand-ins for humans in the laboratory, producing proteins when a laser was shone onto the animals. This innovation "may find utility in the localized delivery of therapeutics," say the researchers.

Real Products, Different Results

by Gwyneth K. Shaw | Jun 15, 2012 10:36 am

(NHI Nanoblog) Its become a rallying cry for some researchers who are scrutinizing the potential health and environmental effects of super-small particles: Test the products that use nanomaterials, not just the substances themselves.

A new study looking at the exposure risk of nano-enabled cosmetic powders offers a powerful validation of that argument. The researchers conclude that the hazards are different from what might be expected, given the size of the particles involved.

They also found that even the rudimentary labeling of nano-enabled products isnt always accurate: Five of the six powders contained nanoparticles, even though only three were marketed that way.

The researchers, from Rutgers University and the Robert Wood Johnson Medical School-University of Medicine and Dentistry of New Jersey, predict that exposure to nanoparticles from cosmetic powders is more likely to be in the upper respiratory system, rather than in the deeper, smaller alveolar area. In other words, these products are mostly coming throughand maybe lodging inyour nose, throat and the bronchial area.

The study was published in Environmental Health Perspectives, an open-access journal put out by the National Institute of Environmental Health Sciences.

Experimental studies using pure versions of nanomaterials suggested that they would migrate to the alveolar region, home of the tiny sacs that form the end of the smallest airways and where the exchange of air and carbon monoxide takes place.

Our findings on potential nanomaterial inhalation exposure due to the use of actual consumer products emphasize that properties and effects of the pure nanomaterial ingredients cannot be used to predict actual consumer exposures and resulting health effects, the authors write. Therefore, experimental techniques for toxicity studies of de facto nanotechnology-based consumer products must be developed. Results of such studies will provide guidance for the developing market of nanotechnology-based consumer products and help clarify the need and feasibility of its regulation.

Nanotechnology is a broad term that encompasses a wide variety of uses of very small materials. (A nanometer is a billionth of a meter.) These substances can make better batteries or lighter and stronger bike frames, as well as new medical instruments and medicines that can save lives. Theyre increasingly common in consumer products, from sunscreens to stain-repellent pants to boat paints that resist algae growth.

Nanomaterials are believed to hold great promise for a wide variety of applications. Their ultra-tiny size often gives them different properties, which is the basis of their appeal; scientists are struggling to figure out whether that can make them dangerous in the process, and how and why it happens.

Taming light with graphene

ScienceDaily (June 20, 2012) Scientists have visualized the trapping and confinement of light on graphene, making a sheet of carbon atoms the most promising candidate for optical information processing on the nano-scale, optical detection, and ultrafast optoelectronics.

Spanish research groups have achieved the first ever visualizations of light guided with nanometric precision on graphene (a one-atom-thick sheet of carbon atoms). This visualization demonstrates what theoretical physicists have long predicted; that it is possible to trap and manipulate light in a highly efficient way, using graphene as a novel platform for optical information processing and sensing. Synergies between theoretical proposals from IQFR-CSIC (Madrid), specializations in graphene nano-photonics and nano-optoelectonics at ICFO (Barcelona), and experimental expertise in optical nano-imaging at nanoGUNE (San Sebastian) give rise to these noteworthy results reported in Nature this week in a back-to-back publication alongside a similar study by the group of Dmitry Basov in UCSD in California.

Graphene is a material that, among many other fascinating properties, has an extraordinary optical behavior. Particularly interesting optical properties had been predicted for the case that light couples to so-called plasmons, wave-like excitations that were predicted to exist in the "sea" of conduction electrons of graphene. However, no direct experimental evidence of plasmons in graphene had been shown up to this work. This is because the wavelength of graphene plasmons is 10 to 100 times smaller than what can be seen with conventional light microscopes.

Now, the researchers show the first experimental images of graphene plasmons. They used a so called near-field microscope that uses a sharp tip to convert the illumination light into a nanoscale light spot that provides the extra push needed for the plasmons to be created. At the same time the tip probes the presence of plasmons. Rainer Hillenbrand, leader of the nanoGUNE group comments: "Seeing is believing! Our near-field optical images definitely proof the existence of propagating and localized graphene plasmons and allow for a direct measurement of their dramatically reduced wavelength."

As demonstrated by the researchers, graphene plasmons can be used to electrically control light in a similar fashion as is traditionally achieved with electrons in a transistor. These capabilities, which until now were impossible with other existing plasmonic materials, enable new highly efficient nano-scale optical switches which can perform calculations using light instead of electricity.

"With our work we show that graphene is an excellent choice for solving the long-standing and technologically important problem of modulating light at the speeds of today's microchips," says Javier Garca de Abajo, leader of the IQFR-CSIC group. In addition, the capability of trapping light in very small volumes could give rise to a new generation of nano-sensors with applications in diverse areas such as medicine and bio-detection, solar cells and light detectors, as well as quantum information processing. This result literally opens a new field of research and provides a first viable path towards ultrafast tuning of light, which was not possible until now. Frank Koppens, leader of the ICFO group, summarizes: "Graphene is a novel and unique material for plasmonics, truly bridging the fields of nano-electronics and nano-optics."

International Nanomedicine Conference bound for Sydney: July 2-4, 2012

Public release date: 19-Jun-2012 [ | E-mail | Share ]

Contact: Myles Gough myles.gough@unsw.edu.au 61-029-385-1933 University of New South Wales

With advances in nanotechnology, the future of medicine is taking shape on the nano-scale and making possible healthcare solutions once confined to the realm of science fiction.

From microscopic robots that could soon be swimming around our bloodstream repairing cells and diagnosing diseases, to drugs with improved therapeutic properties that can selectively target affected regions of the body with cellular precision without damaging surrounding tissue.

The Australian Centre for Nanomedicine at the University of New South Wales is at the forefront of this exciting new discipline and will host the third International Nanomedicine Conference from 2 4 July in Sydney.

The conference will bring together world-leading academics and clinicians to highlight important research into targeted drug delivery systems, diagnostics and imaging, and regenerative medicine, all enabled by nanomedicine.

One nanometre is equivalent to one-billionth of a metre and is roughly 60,000 times thinner than a human hair, or the size of a single strand of DNA.

By exploiting the novel biological, chemical and physical properties of materials at this scale, researchers can build devices and systems that improve disease detection and develop more effective therapies.

The Australian Centre for Nanomedicine at UNSW, which crosses medicine, science and engineering, is investigating strategies to better diagnose and treat illnesses such as cancer, diabetes, multiple sclerosis, Alzheimer's and Parkinson's disease.

STDs blocked by nano gel, study suggests

Women someday could protect themselves against sexually transmitted infections by using a gel that uses nanoparticles to deliver drugs to the vaginal walls, a new study in mice suggests.

Researchers used the gel to deliver an anti-herpes drug to the mice and found that the technology tripled the level of protection that the drug normally provides against aherpes infection.

It's possible the gel's protection could be made to be long-lasting, so it could be applied hours before sexual intercourse, according to the study, which appears today (June 13) in the journal Science Translational Medicine.

If the gel is found fit for human use, the composition of the gel makes it likely that a woman could use it discreetly, without her partner noticing it, the researchers added.

To see just how much the nanoparticle delivery system improved a drug's effectiveness, the researchers purposefully chose an anti-herpes medication that was not particularly effective, and a strain of herpes virus that was remarkably infectious.

"We could protect animals fairly well, with a wimpy drug, against a strong herpes infection," said study researcher Justin Hanes, director of the Center for Nanomedicine at the John Hopkins School of Medicine.

The research has yet to be tried in people, and rodent studies often don't hold up in humans. Under ideal circumstances, clinical trials of the gel could be possible within a year or two, Hanes said.

The trick to developing the gel was making the particles small enough and slick enough to get through the mucus that coats the inside of the vagina. Hanes likened the problem to a bug trying to fly through a spider web.

"There could be a bug that's small enough to fit through a spider web, but that doesn't mean it will get through without getting stuck," he said. But with small, "non-sticky" nanoparticles, the drug was evenly applied across nearly 100 percent of the vaginal surface a feat given the vagina's complex, folding walls, Hanes said.

When they applied the anti-herpesdrug to mice, the researchers found that the drug's effectiveness in preventing herpes increased from 16 percent without the nanoparticles, to 53 percent with the nanoparticles.

How worms are pioneering remote control medicine

If you want to make the worm turn, try using magnets. By implanting nanoparticles in nerve cells in a nematode's head, Arnd Pralle and his team from the State University of New York in Buffalo can make a wriggling worm alter its course when exposed to a magnetic field.

In this video, you can see how both a single treated worm, as well as a whole group, can quickly be triggered to change direction. A third clip shows that in the same scenario, an untreated worm doesn't alter its behaviour.

These nematodes are just one example of how living cells can be controlled remotely. By using other hosts, and implanting nanoparticles in ion channels, DNA strands or antibodies, medical treatments could be activated instantly from afar, leading to a new generation of drugs that can be set off with a smartphone app.

In Switzerland, more than 20,000 people (37% of all deaths) die of cardiovascular disease caused by atherosclerosis each year. Treatment options are currently available to people who suffer from the disease but no drug can target solely the diseased areas, often leading to generalized side effects. Intravenous injection of a vasodilator (a substance that dilates blood vessels), such as nitroglycerin, dilates both the diseased vessels and the rest of our arteries. Blood pressure can thus drop, which would limit the desired increased blood flow generated by vasodilatation of diseased vessels and needed for example during a heart attack.

In order to increase the effectiveness of treatments against atherosclerosis and to reduce side effects, a team of researchers from UNIGE, HUG and the University of Basel have developed nanocontainers having the ability to release their vasodilator content exclusively to diseased areas.

Nanotechnology in medicine

Though no biomarker specific to atherosclerosis has been identified, there is a physical phenomenon inherent to stenosis (the narrowing of blood vessels) known as shear stress. This force results from fluctuations in blood flow induced by the narrowing of the artery and runs parallel to the flow of blood. It is by making use of this phenomenon that the team of researchers has developed a veritable time bomb, a nanocontainer which, under pressure from the shear stress in stenosed arteries, will release its vasodilator contents.

By rearranging the structure of certain molecules (phospholipids) in classic nanocontainers such as liposome, scientists were able to give them a lenticular shape as opposed to the normal spherical shape. In the form of a lens, the nanocontainer then moves through the healthy arteries without breaking. This new nanocontainer is perfectly stable, except when subjected to the shear stress of stenosed arteries. And that's exactly the intention of this technological advance. The vasodilator content is distributed only to the stenotic arteries, significantly increasing the efficacy of the treatment and reducing side effects. In brief, we exploited a previously unexplored aspect of an existing technology. This research offers new perspectives in the treatment of patients with cardiovascular disease, explains Andreas Zumbuehl from the Department of Organic Chemistry at UNIGE.

Nanomedicine is a discipline stemming from general nanoscience but which orients itself towards medical research. The interdisciplinary collaboration between chemistry, physics, basic science and clinical medicine in a highly technical environment could lead to a new era of research, states Till Saxer of the Cardiology and General Internal Medicine Departments at HUG.

The nano component is present in all disciplines, but the most interesting aspect of nanomedicine is its overview allowing the development of clinical products that integrate this global medical point of view from the earliest onset of research projects, states Bert Mller, Director of the Biomaterials Science Centre (BMC) at Basel.

Atherosclerosis, resulting in a narrowing of the arteries and the development of cardiovascular disease, is the leading cause of death worldwide. Until now, no treatment could target diseased areas exclusively, in order to increase drug efficacy and reduce side effects. To help bridge this gap, a group of Swiss researchers from UNIGE, HUG and the University of Basel have developed a veritable 'time bomb,' a treatment that can recognize the diseased areas and treat only them.

In Switzerland, more than 20,000 people (37% of all deaths) die of cardiovascular disease caused by atherosclerosis each year. Treatment options are currently available to people who suffer from the disease but no drug can target solely the diseased areas, often leading to generalized side effects.

How did scientists manage to change the shape of the nanocontainers so that they resemble a lens? By rearranging the structure of molecules, chemists at UNIGE replaced the ester bond that links the two parts of the phospholipid (head and tail), with an amide bond, an organic compound that promotes interaction among phospholipids. Once modified, the molecules are hydrated then heated to form a liquid sphere which will relax to solidify in the form of a lens upon cooling.

Asia's First Graphene Nano-Tech Facility Opens In Singapore

SINGAPORE, June 13 (Bernama) -- A S$15 million Micro and Nano-Fabrication facility has opened at the National University of Singapore's (NUS) Graphene Research Centre, the first nano-science and nano-technology facility of its kind in Asia dedicated to graphene.

The Centre, set up in August 2010 as part of the NUS Faculty of Science, is involved in projects totalling over S$100 million, and aims to be a world leader in the emerging field of graphene research.

Helmed by Professor Antonio H. Castro Neto, who is one of the world leaders in graphene research, the Centre is set up under scientific advising by Professors Andre Geim and Konstantin Novoselov, from Manchester University in the UK and winners of the 2010 Nobel Prize in Physics for the discovery of graphene.

NUS President Professor Tan Chorh Chuan said: "Graphene is one of the most interesting and promising materials of our time although its unique properties have yet to be fully explored.

"We look forward to seeing novel discoveries and innovative breakthroughs emerge from the Centre, putting Singapore in the forefront of research in revolutionary new materials."

There is an intense global drive towards graphene commercialisation. Graphene grown by chemical vapour deposition (CVD) could be a game changer in the industry of transparent conductive coatings (TCC) essential for the modern display, lighting touch panel, and photovoltaic industries. This market is expected to reach annually US$55 billion by 2020.

Solution-processed graphene is expected to have a major impact on batteries, catalysts and composite materials, reaching a projected market value of US$675 million in 2020.

Neto said: "Our research addresses immediate growth, synthesis, transfer and doping problems of existing approaches. We aim to break current technological bottlenecks for industry adoption by meeting the industrial benchmarks of conductivity and optical transparency for graphene and by improving size and conductivity of graphene flakes from solution at a low cost.

Jugaad innovators don't plan – they improvise

Jugaad innovators don't plan - they improvise By demonstrating agility, jugaad innovators can deal with unanticipated challenges faster and seize unexpected opportunities-such as changing customer needs-more swiftly than their competitors Jugaad Innovation / Jun 04, 2012, 00:45 IST

Emerging markets are characterized by high volatility. Economic circumstances are constantly changing. Growth rates are often in double digits, and the competitive landscape is often shifting. New laws and regulations are constantly being put into place, and policy is constantly evolving. So jugaad innovators need to experiment as they go along and be willing to try multiple options, rather than adopting one approach at the start and sticking to it thereafter. Unlike their counterparts in Silicon Valley, jugaad innovators do not attempt to work everything out in advance or rely on a business plan to determine the mid- to long-term roadmap for their new ventures. Instead, they improvise their next course of action as circumstances change, and they do so from within a framework of deep knowledge and passion. Their approach is in fact more akin to a jazz band than to an orchestra: everything is improvised, fluid, and dynamic. As such, their strategies are organic and emergent rather than predetermined. Jugaad innovators flexible thinkingtheir ability to improviseserves them especially well when confronted with adversity.

Given their propensity for improvisation, jugaad innovators dont rely on forecasting tools like scenario planning, as many companies do, to assess future risks. They believe in Murphys Lawanything that can go wrong will go wrongso whats the point of anticipating every single obstacle that might appear down the road? Jugaad innovators dont have a Plan B, let alone a Plan C. Rather, when confronted with an unexpected hindrance, they rely on their innate ability to improvise an effective solution to overcome it, given the circumstances at that time.

In 2007, however, local farmers began protesting against the acquisition of land for the factory. The dispute rapidly escalated into a political issue and caught Tata Motors off guard. As the protests intensified through 2008, Ravi Kant, then managing director of Tata Motors (and later its non-executive vice chairman) made a bold decision. He set aside his firms prior manufacturing plans and swiftly shifted the production of the Nano to Sanand, in the investor-friendly state of Gujarat, on the other side of the country. He didnt hire a management consultant to advise him on the move; he just trusted his instinct that this was the right thing to do, given the circumstances. In just fourteen months (compared to the expected twenty-eight months for the Singur plant), Tata Motors built a new factory in Sanand, Gujarat. The new factory began production of Nanos in June 2010.

One year later, Ravi Kant and his team had to demonstrate the ability to adapt to rapidly changing circumstances yet again: the Nanos werent selling as well as expected. Monthly sales had fallen well below the optimistic forecast of twenty thousand units. Rather than being disappointed by the Nanos lackluster performance, Tata Motors leadership used this early market feedback to improvise a plan to shore up sales. Ratan Tata originally envisioned a distributed supply chain model whereby Tata Motors would dispatch flat packs to local entrepreneurs across the country, who would do the final assembly of Nanos close to customers thus creating gainful employment in local communities. With flagging sales, however, this original vision had to be revised: Tata Motors executives went back to the drawing board and quickly revamped Nanos logistics network to a more straightforward one, which involved manufacture and assembly at one site in Gujarat, and distribution through a traditional dealer network throughout the country. But again Tata Motors hit a snag: rural customers such as farmers were not venturing into Tata Motors showrooms in small towns. Among other things, they felt intimidated by dealers dressed in suits and ties.

This setback led Tata Motors management to redesign their rural showrooms to make them more informal-for example by staffing them with casually attired salesmen who could pitch the Nano to Indian farmers over a cup of chai. Tata Motors also launched a nationwide TV campaign and began offering consumer financing at highly attractive rates to lure frugal Indian consumers. By constantly adapting and refining its business modeland implementing changes within weeks, not monthsTata Motors invigorated sales of the Nano, which, although still lower than expected, are gradually beginning to pick up. Indeed, it is very likely that the future success of the car will depend on more such quick adaptation and flexible thinking by the managers of Tata Motors.

Jugaad innovators experiment with multiple ways to reach a goal Unpredictability is the norm in emerging markets. Because of diversity and rapid change, it is hard to predict how consumers will respond to new products and services-and how new business strategies will perform in, say, rural markets. Jugaad innovators may have a single-minded vision of where they want to get to, but they must be willing to try different paths to get there. Specifically, they must be willing to keep experimenting in order to attain their goalsand they must be flexible enough to quickly switch from one path to another along the way.

Dr Mohan, for instance, experimented with a number of different ways to frugally yet effectively engage rural communities both as consumers (patients) and employees. When he first sent his expensive technicians from his city hospital to work in remote villages, he found that these techniciansalthough highly competentwould soon leave, wanting to return to city life. Learning this, he developed a training curriculum in his city hospital to impart to young men and women from villages the basic skills they need as healthcare workers. After about three months, these newly trained healthcare professionals would return to their rural homes, where they were more likely to want to remain. This in turn helped reduce costs and turnover in Dr Mohans model. Dr Mohan had a similar experience with his attempts to work with non-traditional partners to develop a cost-effective tele-medicine platform. Although he initially contemplated partnering with more typicaland expensivetechnology providers, Dr Mohan eventually linked up with ISRO, which provides his roaming tele-medicine van with a free satellite uplink to his clinic in the city of Chennai.

Jugaad innovators act with speed and agility In emerging markets, new threats and opportunities can emerge from out of the blue. This forces jugaad innovators to not only think but also act flexibly. By demonstrating agility, jugaad innovators can deal with unanticipated challenges faster and seize unexpected opportunitiessuch as changing customer needsmore swiftly than their competitors. Zhang Ruimin is one such jugaad innovator who thinks and acts quickly.

Zhang, is the CEO of Haier, a Chinese consumer goods company that is making appliance makers like GE and Whirlpool nervous. Under Zhangs leadership, Haier has, in the space of a decade, made huge inroads into North American and European markets by selling quality appliances at lower prices than those of Western suppliers like Whirlpool and GE. Armed with its value for money strategy, Haier is disrupting the consumer goods market not only in mainstream segments like air-conditioners and washing machines, but also in niche segments like wine coolers. For instance, Haier launched a $704 (Rs 35,200) wine cooler that is less than half the cost of industry leader La Sommelires product. Within two years of this launch, Haier has grown the market by a whopping 10,000 percent and now controls 60 percent of the US market by value. By leveraging its value for money strategy, Haier has also rapidly established a strong presence in the Indian home appliances market, where it commands 8 percent of market share. In coming years, Haier aims to grow its Indian market share to at least 10 percent and achieve Rs 4,500 crore in revenue and become one of the top five brands in India by 2014.
