(Phys.org)—Researchers have created a new type of miniature pump activated by body heat that could be used in drug-delivery patches powered by fermentation. http://phys.org/news266589872.html Chemistry Tue, 11 Sep 2012 13:44:46 EST news266589872 Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and without need for refrigeration. The tiny needles can be fabricated under normal temperature and pressure and from water, so they can be loaded with sensitive biochemical compounds and maintain their activity prior to use. They are also biodegradable and biocompatible. http://phys.org/news243696539.html Chemistry Wed, 21 Dec 2011 13:30:01 EST news243696539 (PhysOrg.com) -- Purdue University researchers have developed a new type of pump for drug-delivery patches that might use arrays of "microneedles" to deliver a wider range of medications than now possible with conventional patches. http://phys.org/news202543380.html Chemistry Wed, 01 Sep 2010 07:03:26 EST news202543380 Researchers from North Carolina State University have developed extremely small microneedles that can be used to deliver medically-relevant nanoscale dyes called quantum dots into skin - an advance that opens the door to new techniques for diagnosing and treating a variety of medical conditions, including skin cancer. http://phys.org/news201950905.html Nanotechnology Wed, 25 Aug 2010 10:28:44 EST news201950905
