Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine. Their study appears in the Journal of the American Chemical Society. http://www.physorg.com/news175953070.html Nanotechnology Wed, 28 Oct 2009 12:51:49 EST news175953070 Scientists working at Queen Mary, University of London, have developed micrometer-sized capsules to safely deliver drugs inside living cells. http://www.physorg.com/news173681739.html Nanotechnology Fri, 02 Oct 2009 05:56:26 EST news173681739 A tiny particle syringe composed of polymer layers and nanoparticles may provide drug delivery that targets diseased cells without harming the rest of the body, according to a team of chemical engineers. This delivery system could be robust and flexible enough to deliver a variety of substances. http://www.physorg.com/news150984109.html Nanotechnology Mon, 12 Jan 2009 12:01:49 EST news150984109
