For the treatment of complex bone fractures or even missing bone parts, surgeons typically deploy metal implants. In this context, an attractive alternative to the traditional materials like…
Targeting medical treatment to an ailing body part is a practice as old as medicine itself. A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside the body and is not so easy to reach. In such cases, a treatment like surgery or chemotherapy might be called for. A pair of researchers in Caltech's Division of Engineering and…
Melanin protects our skin from the sun’s damaging rays by absorbing light energy and converting it to heat.

The UConn research is featured in the current online issue of the Proceedings of the National Academy of Sciences. The small, flexible sensor is…
For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…

The UK's MRSA rates have been declining since 2006 — and this year could be 50% lower than in 2004. This increasing control over dangerous pathogens has not been achieved without considerable hospital staff efforts, relentless public and government pressures on them, and in-house malcontent about the out-sourcing of cleaning work. Given the cost of nosocomial infections to patients, the NHS…
Recent studies show that drug-eluting-stents perform superior than bare metal stents in the treatment of high-risk cardiac patients. At ComPaMED 2007, the Germany based company HEMOTEQ, leading designer and manufacturer of ultra-thin coatings for medical devices, presented their solutions for customized coating of stents.
Coronary stents provide wall wrapping of dissection, prevent elastic recoil, and reduce restenosis after percutaneous transluminal coronary angioplasty. In addition, drug eluting stents loaded with antiproliferative agents inhibit intimal hyperplasia and offer a further reduction of restenosis.
