Rice student earns top Texas nano honors
The Nanotechnology Foundation of Texas (NFT) has awarded Rice University doctoral student Vinit Murthy its 2006 George Kozmetsky Award for Outstanding Graduate Research in Nanotechnology for his co-discovery of a simple method to encapsulate any water-soluble compound easily and without damage. The Kozmetsky Awards, given annually to two Texas graduate students, are the first of their kind to be offered in the US to students working in nano-related fields. (2006-01-30)

New 'self-exploding' microcapsules could take sting out of drug delivery
Belgian chemists have developed (2006-01-03)

Rice unveils 'green' microcapsule production method
Chemical engineers from Rice University have unveiled the most environmentally sensitive approach yet devised for making tiny hollow spheres called microcapsules. Dozens of companies are developing microcapsules - usually smaller than living cells - to deliver everything from drugs and imaging agents to perfumes and flavor enhancers. In this month's Advanced Materials, Rice's team describes a mix-and-shake procedure that produces microcapsules almost instantly at room temperature, under normal pressure, in water, and at mild pH values.

Rice's CNST awards Smalley/Curl funds for innovation
Rice University's Center for Nanoscale Science and Technology today awarded the first two grants from its Smalley/Curl Fund for Innovation. One went to a chemist developing self-assembly methods for targeted drug delivery and encapsulation applications, and the second went to a bioengineer and physicist who are studying the optical properties of gold nanorods. The one-year, $15,000 grants are designed to provide seed funds for the development of novel ideas that have broad potential in nanotechnology. (2005-02-07)

Transplant of pig tissue may reduce stroke size and damage
A tiny capsule containing tissue that secretes a cocktail of brain-nourishing neurotrophic factors may one day help reduce the damage and disability of stroke, according to research published in the September issue of Stroke. (2004-09-01)

Tissue involved in brain development may offer new approach to stroke treatment
The same tissue that helps a developing brain form its protective blood-brain barrier may protect the adult brain from the ravages of stroke, researchers say. (2004-05-06)

One-shot addiction treatment shows promise
A study in the January issue of Drug and Alcohol Dependence reports that a long-lasting depot medication appears safe and effective for treatment of narcotic addiction. In the study, conducted by researchers of the Johns Hopkins University School of Medicine, a single depot injection of 58 mg of buprenorphine prevented withdrawal discomfort for 6 weeks in heroin-dependent patients, reduced the effects of injected opiates, and provided a comfortable detoxification as it gradually wore off.

Purdue Research Park company makes melt-in-your-mouth meds
A Purdue Research Park startup company is ready to market a new drug-delivery technology that will make it easier for people to take medicines in pill form. Researchers at Akina Inc. are developing Purdue University-licensed technologies that improve the ways in which prescription drugs, over-the-counter medicines and even vitamins are administered orally. The venture's latest technology, called Frosta(tm), involves tablet formulations that can melt in a patient's mouth as quickly as 10 seconds. (2003-08-04)

Fabricated microvascular networks could create compact fluidic factories
Using direct-write assembly of organic ink, researchers at the University of Illinois at Urbana-Champaign have developed a technique for fabricating three-dimensional microvascular networks. These tiny networks could function as compact fluidic factories in miniature sensors, chemical reactors, or computers used in applications from biomedicine to information technology. (2003-03-23)

Medical microspheres provide precision-release drug delivery
The elusive goal of controlling the release rate of encapsulated compounds for the precise delivery of drugs over a prolonged period is finally within reach. University of Illinois researchers have developed a method for making drug-encapsulated, biodegradable polymer microspheres that provides precise control over sphere size and shell thickness. (2002-04-09)

Tissue engineering could become new coronary bypass
A spongy plastic material impregnated with two kinds of growth factor has been shown to encourage the formation of healthy new blood vessels in living rats, according to a tissue engineering research team at the University of Michigan. (2001-11-14)

Colourful e-paper
It will soon be possible to surf the Web on colourful sheets of electronic paper. E Ink of Boston have succeeded in making e-paper work in full colour and hope eventually to make a floppy version to substitute ordinary paper. (2001-06-05)

Mimicking biological systems, composite material heals itself
Inspired by biological systems in which damage triggers an autonomic healing response, researchers at the University of Illinois have developed a synthetic material that can heal itself when cracked or broken. (2001-02-13)

Divers may soon wax lyrical about some new hot installation -- The water's fine
Frigid ocean depths may become more hospitable for scuba divers that have to spend hours underwater, thanks to the US Navy. Divers wear dry suits containing bits of wax which melt and freeze as the temperature changes, radiating heat back to the diver. (1999-06-24)

Encapsulating Insulin-Producing Cells For Possible Diabetes Therapy
Duke University chemists led by assistant professor Mark Grinstaff are developing novel liquid polymers that can be solidified by a quick flash of laser light to seal transplanted insulin-producing cells inside a selectively permeable capsule, thus preventing rejection by diabetics' immune systems.
