Breakthrough solutions for HAMR nanoantenna for next-generation ultra-high density magnetic storage

18 hours ago by Emil Venere

Researchers at Nano-Meta Technologies Inc. (NMTI) in the Purdue Research Park have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today’s computers.

The new technology could make it possible to record data on an unprecedented small scale using tiny “nanoantennas” and to increase the amount of data that can be stored on a standard magnetic disk by 10 to 100 times.

The storage industry’s technology strategy, called heat-assisted magnetic recording (HAMR), hinges on the design of the nanoantenna, or near-field transducer (NFT), said Urcan Guler, chief scientist at Nano-Meta Technologies.

HAMR harnesses “plasmonics,” a technology that uses clouds of electrons called surface plasmons to manipulate and control light. However, some of the plasmonic NFTs under development rely on the use of metals such as gold and silver, which are not mechanically robust and present a challenge in fabrication and long-term reliability of the HAMR recording head.

Researchers from Nano-Meta Technologies and Purdue University are working to replace gold with titanium nitride. The material offers high strength and durability at high temperatures, and its use as a nanoantenna paves the way for next-generation recording systems, said Vladimir M. Shalaev, scientific director of nanophotonics at Purdue’s Birck Nanotechnology Center and a distinguished professor of electrical and computer engineering.

The researchers have modified the physical properties of titanium nitride, tailoring it for HAMR.

A team from Nano-Meta Technologies and Purdue has authored an article on the need to develop new materials as alternatives to gold and silver for various plasmonic applications, using HAMR as an example. The article was published online this month in the journal Faraday Discussions.

The technology could make it possible to circumvent the disk-storage-capacity limits imposed by conventional magnetic recording materials. Normally, lenses cannot focus light smaller than the wavelength of the light itself, which is hundreds of nanometers across. However, nanoantennas allow light to be focused into spots far smaller than the wavelength of light, making it possible to increase the storage capacity of the medium.

Industry has been reluctant to adopt titanium nitride for potential new plasmonic applications because making nanoantennas out of conventional titanium nitride leads to excessive “self-heating” through absorption of the input laser light, hindering performance. Common titanium nitride also undergoes oxidation reactions at high temperatures that degrade its optical properties, said Ernesto Marinero, a professor in Purdue’s School of Materials Engineering who is an expert in magnetic recording and joined the university after a long career in the storage industry.

With deregulation in diesel prices, a Nano diesel does not make sense with the lesser difference in petrol and diesel fuel prices and it only made sense for Tata to stop the development on the lost cause.

The Nano diesel has been a long awaited offering from Tata Motors that will now not see the light of the day.

A recent report suggests that Tata has indefinitely halted the development of the Nano diesel as its Engineering Research Centre (ERC) at Pimpri, Pune in order to focus on other projects instead.

In addition to the Nano diesel, the company has also stopped the development of a quadricycle based on the Magic Iris platform at the ERC for unknown reasons.

Starting with the Tata Nano Diesel, the model has been long in the news with the automaker developing the same since quite some time now.

However, the extensive development has taken a toll on Tata as diesel prices have now been deregulated with the difference between petrol and diesel coming down to a minimal.

Bio-Inspired 'Nano-Cocoons' Offer Targeted Drug Delivery Against Cancer Cells

Contact Information

Available for logged-in reporters only

Newswise Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale cocoons made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs. The work was done by researchers at North Carolina State University and the University of North Carolina at Chapel Hill.

This drug delivery system is DNA-based, which means it is biocompatible and less toxic to patients than systems that use synthetic materials, says Dr. Zhen Gu, senior author of a paper on the work and an assistant professor in the joint biomedical engineering program at NC State and UNC Chapel Hill.

This technique also specifically targets cancer cells, can carry a large drug load and releases the drugs very quickly once inside the cancer cell, Gu says.

In addition, because we used self-assembling DNA techniques, it is relatively easy to manufacture, says Wujin Sun, lead author of the paper and a Ph.D. student in Gus lab.

Each nano-cocoon is made of a single strand of DNA that self-assembles into what looks like a cocoon, or ball of yarn, that measures 150 nanometers across.

The core of the nano-cocoon contains the anticancer drug doxorubicin (DOX) and a protein called DNase. The DNase, an enzyme that would normally cut up the DNA cocoon, is coated in a thin polymer that traps the DNase like a sword in a sheath.

The surface of the nano-cocoon is studded with folic acid ligands. When the nano-cocoon encounters a cancer cell, the ligands bind the nano-cocoon to receptors on the surface of the cell causing the cell to suck in the nano-cocoon.

Once inside the cancer cell, the cells acidic environment destroys the polymer sheath containing the DNase. Freed from its sheath, the DNase rapidly slices through the DNA cocoon, spilling DOX into the cancer cell and killing it.

New knowledge of cannabis paves the way for drug development

PUBLIC RELEASE DATE:

8-Sep-2014

Contact: Rikke Byesen rb@nano.ku.dk 452-875-0413 Faculty of Science – University of Copenhagen

Revolutionary nanotechnology method could help improve the development of new medicine and reduce costs. Researchers from the Nano-Science Center and the Department of Chemistry at the University of Copenhagen have developed a new screening method that makes it possible to study cell membrane proteins that bind drugs, such as cannabis and adrenaline, while reducing the consumption of precious samples by a billion times.

About 40% of all medicines used today work through the so-called “G protein-coupled receptors”. These receptors react to changes in the cell environment, for example, to increased amounts of chemicals like cannabis, adrenaline or the medications we take and are therefore of paramount importance to the pharmaceutical industry.

“There is a lot of attention on research into “G protein-coupled receptors”, because they have a key roll in recognizing and binding different substances. Our new method is of interest to the industry because it can contribute to faster and cheaper drug development”, explains Professor Dimitrios Stamou, who heads the Nanomedicine research group at the Nano-Science Center, where the method has been developed. The new method is described in a publication at the esteemed scientific journal Nature Methods.

Cheaper to test and develop medicine

The new method will reduce dramatically the use of precious membrane protein samples. Traditionally, you test a medicinal substance by using small drops of a sample containing the protein that the medicine binds to. If you look closely enough however, each drop is composed of thousands of billions of small nano-containers containing the isolated proteins. Until now, it has been assumed that all of these nano-containers are identical. But it turns out this is not the case and that is why researchers can use a billion times smaller samples for testing drug candidates than hitherto.

“We have discovered that each one of the countless nano-containers is unique. Our method allows us to collect information about each individual nano-container. We can use this information to construct high-throughput screens, where you can, for example, test how medicinal drugs bind G protein-coupled receptors”, explains Signe Mathiasen, who is first author of the paper describing the screening method in Nature Methods. Signe Mathiasen has worked on developing a screening method over the last four years at the University of Copenhagen, where she wrote her PhD thesis research project under the supervision of Professor Stamou.

World's Smallest Nanomotor Spins as Fast as a Jet Engine

By Lance Ulanoff2014-05-21 17:12:35 UTC

Researchers in Texas have created the nano-version of the Energizer Bunny. Their new nanomotor rotates at 18,000 RPMs for a whopping 15 hours. Previous nanomotors rotated far more slowly and sputtered out after a few minutes.

The tiny technology, also known as “Ultrahigh-Speed Rotating Nanoelectromechanical System (NEMS)” is a potential breakthrough for treating all kinds of human ailments including, you guessed it, cancer. Built by a team at Cockrell School of Engineering at The University of Texas at Austin and led by Dr. Donglei (Emma) Fan, the motor is actually a collection of nano-entities, including a nanowire and patterned nano magnets.

In their research paper, the engineers recount all the less successful previous nano-work the new nanomotor is built upon, including experiments from Cornell University where out of hundreds of synthesized nanomotors, only a few rotated and at UC Berkeley, which built an excellent nanomotor using electron-beam lithography that, unfortunately, required an overly complex fabrication procedure.

Cockrell’s nanomotor, however, is built more simply and effectively in part because of another Cockrell invention, Electric Tweezers, a nano-manipulation technique that allowed the team to not only transport the nano-entities, but precisely position them within 150 nanometers and then rotate them exactly how they wanted.

Not only can these nanomotors rotate like nobody’s nano-business (almost as fast as a Lear jet engine), a group of them can do it in sync. At 500 times smaller than a grain of salt, these nanomotors could one day work inside cells and spin together to deliver cancer-killing medicines.

The future, however, is even crazier. Researchers envision building entire nano robots out of a group of these nanomotors, which can then work together to diagnose, grab and treat cells.

The nanomotor joins an ever-growing list of nano-breakthroughs. Earlier this year, researchers in Denmark built a drug-delivery cage out of DNA. Maybe one day the nanomotors will go to work while carrying these nanocages.

IBM 3D Prints World's Smallest Magazine Cover

By Lance Ulanoff2014-04-25 13:30:33 UTC

At the intersection of nano technology and 3D printing lies IBM’s Microscopic 3D Printer, which now holds the distinction of printing the smallest magazine cover in the world.

IBM and National Geographic Kids unveiled the cover, which is small enough to fit on a single grain of salt 2,000 times, at the USA Science and Engineering Festival in Washington, D.C., where The Guinness Book of World Records officially proclaimed it as the world’s smallest magazine cover.

The gray-scale duplication of NatGeo Kids’ cover is actually invisible to the naked eye. Dr. Colin Rawlings, a physicist at IBM Research, said that even with a microscope, you’d only be able to make our a blurry image. To see it in full, you need an electron microscope.

The National Geographic Kids nano-printed cover (left) alongside the original.

IBM used a special kind of nano-printer which, unlike traditional 3D printers that print layer-by-layer, removes material to create its work. The silicon tip of the nano-printer reaches 1,000 degrees Celsius and literally vaporizes the material in this case, a polymer to create indents of varying depths, depending on the light qualities of each pixel in the original scanned image. Put simply, the nano tip, which is many thousands of times smaller than the tip of a pencil, carves away at the surface to create the final 3D product. It took about 10 minutes to print the black and white replica of the National Geographic Kids cover.

The tiny cover is a fun demonstration of the micro 3D printers capabilities, but its true purpose lies elsewhere. Rawlings said that the printer, which is now being used commercially at the University of McGill in Canada, is a perfect tool for rapid prototyping.

“Scientists make a lot of mistakes so being able to prototype things quickly and accurately is really important and thats what this lets you do,” he said.

Ultimately, the printer could be used to work out the pathways for future processors. IBM’s own newly introduced high-end mainframe processor the Power8, uses a 22 nanometer production process. The micro printer can go as low as 8 nanometers. Ostensibly, this means, the printer is ready to prototype a road map for the future of processors.

Magnetic Medicine: Nanoparticles target cancer-fighting immune cells

Using tiny particles designed to target cancer-fighting immune cells, Johns Hopkins researchers have trained the immune systems of mice to fight melanoma, a deadly skin cancer. The experiments, described on the website of ACS Nano on February 24, represent a significant step toward using nanoparticles and magnetism to treat a variety of conditions, the researchers say.

“Size was key to this experiment,” says Jonathan Schneck, M.D., Ph.D., a professor of pathology, medicine and oncology at the Johns Hopkins University School of Medicine’s Institute for Cell Engineering. “By using small enough particles, we could, for the first time, see a key difference in cancer-fighting cells, and we harnessed that knowledge to enhance the immune attack on cancer.”

Schneck’s team has pioneered the development of artificial white blood cells, so-called artificial antigen-presenting cells (aAPCs), which show promise in training animals’ immune systems to fight diseases such as cancer. To do that, the aAPCs must interact with immune cells known as naive T cells that are already present in the body, awaiting instructions about which specific invader they will battle. The aAPCs bind to specialized receptors on the T cells’ surfaces and “presenting” them with distinctive proteins called antigens. This process activates the T cells, programming them to battle a specific threat such as a virus, bacteria or tumor, as well as to make more T cells.

The team had been working with microscale particles, which are about one-hundredth of a millimeter across. But, says Schneck, aAPCs of that size are still too large to get into some areas of a body and may even cause tissue damage because of their relatively large size. In addition, the microscale particles bound equally well to naive T cells and others, so the team began to explore using much smaller nanoscale aAPCs. Since size and shape are central to how aAPCs interact with T cells, Karlo Perica, a graduate student in Schneck’s laboratory, tested the impact of these smaller particles.

The so-called nano-aAPCs were small enough that many of them could bind to a single T cell, as the team had expected. But when Perica compared naive T cells to those that had been activated, he found that the naive cells were able to bind more nanoparticles. “This was quite surprising, since many studies had already shown that naive and activated T cells had equal numbers of receptors,” Schneck says. “Based on Karlo’s results, we suspected that the activated cells’ receptors were configured in a way that limited the number of nanoparticles that could bind to them.”

To see whether there indeed was a relationship between activation and receptor clustering, Perica applied a magnetic field to the cells, causing the nano-aAPCs to attract one another and cluster together, bringing the receptors with them. The clustering did indeed activate the naive T cells, and it made the activated cells even more active — effectively ramping up the normal immune response.

To examine how the increased activation would play out in living animals, the team treated a sample of T cells with nano-aAPCs targeting those T cells programmed to battle melanoma. The researchers next put the treated cells under a magnetic field and then put them into mice with skin tumors. The tumors in mice treated with both nano-aAPCs and magnetism stopped growing, and by the end of the experiment, they were about 10 times smaller than those of untreated mice, the researchers found. In addition, they report, six of the eight magnetism-treated mice survived for more than four weeks showing no signs of tumor growth, compared to zero of the untreated mice.

“We were able to fine-tune the strength of the immune response by varying the strength of the magnetic field and how long it was applied, much as different doses of a drug yield different effects,” says Perica. “We think this is the first time magnetic fields have acted like medicine in this way.”

In addition to its potential medical applications, Perica notes that combining nanoparticles and magnetism may give researchers a new window into fundamental biological processes. “In my field, immunology, a major puzzle is how T cells pick out the antigen they’re targeting in a sea of similar antigens in order to find and destroy a specific threat,” he says. “Receptors are key to that action, and the nano-aAPCs let us detect what the receptors are doing.”

“We have a bevy of new questions to work on now: What’s the optimal magnetic ‘dose’? Could we use magnetic fields to activate T cells without taking them out of the body? And could magnets be used to target an immune response to a particular part of the body, such as a tumor’s location?” Schneck adds. “We’re excited to see where this new avenue of research takes us.”
