Researchers Made An Edible Battery Out Of Ink

A team of researchers at Carnegie Mellon have developed a biodegradable battery derived from cuttlefish ink.

The Carnegie Mellon team has developed the battery and tested its power storage capacities, but no one has taken the big swallow yet. "I'm thinking about doing it at some point," said Professor Christopher Bettinger, one of the researchers.

The team's findings were recently published in the Proceedings of the National Academy of Sciences (paywall).

The battery could be used to make new medicine delivery systems for drugs that are currently administered as shots. "One of the first applications that we think is going to be interesting is in controlled release," said Bettinger. "Delivering drugs through the oral route can overcome a lot of the challenges that people have with injections."

The biodegradable battery could be used to create controlled release devices that can be swallowed like a pill, but would be able to release medicine after passing through the stomach. Many drugs cannot be taken orally, because they would be destroyed before they could be useful.

Now that the prototype battery has been created, the team is working on delivery systems for specific medical applications. The batteries could power devices that are able to sense where they are in the digestive tract, and deliver things like vaccines or arthritis drugs.

Bettinger explains that these batteries aren't optimized for power density or the ability to be recharged, but rather for bio-compatibility. The sodium-ion batteries are made from melanin and manganese oxide, which break down into nontoxic components. The melanin is derived from cuttlefish ink.The Carnegie Mellon team was interested in using naturally occurring melanin thanks to its "disordered, semi-conducting" nano structure. They found that natural melanin, which is also found in the human body in lower concentrations, has a higher charge storage capacity than lab-made melanin.

Although this battery is made from bio-compatible materials, it may pass through the digestive system without breaking down because the battery doesn't deteriorate particularly quickly. "It's on the order of weeks or months," said Bettinger.

The biodegradable battery makes edible electronics safer for use in the body than conventional batteries. "If it gets stuck in the body, it's not a big deal," he said.

The team is also continuing to research melanin's electro-conductive properties. "If we can understand that process with a higher degree of certainty, then maybe we can engineer new materials that have more interesting properties."

ARTICLE IN PRESS - Nanomedicine

Nano-capsules show potential for more potent chemoprevention

PUBLIC RELEASE DATE:

8-Jan-2014

Contact: Judy Fortin judy.fortin@emory.edu 404-778-4580 Emory Health Sciences

Researchers at the Winship Cancer Institute of Emory University have discovered a more effective drug delivery system using nanotechnology that could one day significantly affect cancer prevention.

The study, published today in Cancer Prevention Research, a journal of the American Association for Cancer Research, involved the use of microscopic amounts of the naturally occurring antioxidant, luteolin, that were encapsulated in a water-soluble polymer. When injected into mice the nano-luteolin inhibited growth of lung cancer and head and neck cancer cells.

"Our results suggest that nanoparticle delivery of naturally occurring dietary agents like luteolin has many advantages," says senior study author Dong Moon Shin, MD, professor of hematology and medical oncology at Emory University School of Medicine and associate director of academic development at Winship Cancer Institute. "By using a high concentration of luteolin in the blood, we were better able to inhibit the growth of cancer cells."

Luteolin is known for its anti-inflammatory and anti-cancer effects. It is naturally found in green vegetables such as broccoli, celery and artichokes, however, Shin says large quantities would need to be consumed to be effective. By concentrating the compound into a nanoparticle and making it easy to dissolve in water, researchers conclude nano-luteolin has immense potential for future human studies of chemoprevention

Chemoprevention is currently used to help stop the recurrence of cancer in patients and reduce the risk of cancer in others.

:: 06, Jan 2014 :: NEW PACKAGING PLASTIC THAT PROTECTS AS GOOD AS ALUMINIUM FOIL

Tera-Barrier Films invents alternative stretchable plastic for prolonging shelf-life of pharmaceuticals, food and electronics~

1. 06 January 2014 Tera-Barrier Films (TBF) Pte Ltd, a spin-off company from A*STARs Institute of Materials Research and Engineerings (IMRE), has invented a new plastic film using a revolutionary nano-inspired process that makes the material thinner but as effective as aluminium foil in keeping air and moisture at bay. The stretchable plastic could be an alternative for prolonging shelf-life of pharmaceuticals, food and electronics, bridging the gap of aluminium foil and transparent oxide films.

2. The new plastic by TBF has one of the lowest moisture vapour transmission rates (mvtr), preventing air and moisture from penetrating the layer. The plastic has an air and moisture barrier that is about 10 times better than the transparent oxide barriers which are currently being used to package food and medicines owing to its uniquely encapsulated nanoparticle layer. The film has been validated by a number of companies and potential commercialisation partners.

3. TBFs 700nm encapsulated nanoparticle barrier films - which are thinner than a strand of human hair - have high transparency and are also stretchable, features not possible with aluminium-based packaging material. Inorganic barrier thin films are highly transparent but have lower barrier property and are not stretchable. TBFs films will allow see-through packing and a longer shelf-life for a wide range of products from high-end electronics to perishable goods. Stretchability is another attractive feature in facilitating simple packaging processes.

4. Aluminium as a metal has very high oxygen and moisture barrier properties, but aluminium-based packaging comes at a higher processing cost, is opaque, non-stretchable, and interferes with electronics, making the integration of components like RFID devices difficult. TBFs new stretchable thin films are cost effective and transparent, with barrier properties comparable to that of aluminium foil.

Nano medicine – hope and future for cancer

Mysore, march 21, 2013, DHNS:

Tapas K Kundu from JNCASR, Bangalore, said gold nano-particles can reduce cancer, but the challenge in containing adverse reactions of these particles, which the body considered as foreign particles.

Kundu, a professor with the molecular biology and genetics unit of JNCASR, said that the challenge was to make the drug reach cancer stems cells (CSC).

He was delivering a lecture on Genes and Diseases: New Generation Therapeutics, organised by Centre for Nano-technology as part of an Expert Lecture Series, at Sir M V Auditorium of National Institute of Engineering (NIE) in Mysore recently.

Among all diseases, more money has been pumped into cancer for research and yet only two per cent success rate has been achieved. There are 100 different diseases that begin in the cells. Hence extensive research is going on all over the world in the area of cancer. New lifestyle and lack of awareness have resulted in high levels of cancer incidents in India. All types of cancer are genetic, but not hereditary though some cancers sometimes are hereditary, he said.

Evidence of cancer was available in dinosaur bones, which date back to 80 million years. In 300 BC, Hippocrates named tumors as carcinogens. However, it may be noted that much before Hippocrates, tumors were referred to as arbudha in Ayurvedic science, he said.

Kundu said, any irritation be it psychological or physical can lead to cancer. The imbalance in hormones was a strong pointer to cancer. Unfortunately, oral and cervical cancers are predominant in India. A day will come when we will have to live with cancer like we do with diabetes and hypertension. Therefore, nano medicine is the new hope and future, he added.
