The Project on Emerging Nanotechnologies (PEN) has developed findNano, an application for Apple's iPhone and iPod Touch that lets users discover and determine whether consumer products are nanotechnology-enabled. Nanotechnology, the emerging technology of using materials by engineering them at an incredibly small scale, has applications ranging from consumer electronics to improved drug delivery systems. http://www.physorg.com/news177249579.html Nanotechnology Thu, 12 Nov 2009 12:30:03 EST news177249579 Clemson bioengineer Frank Alexis is designing new ways to target drugs and reduce the chances for side effects. http://www.physorg.com/news174219683.html Nanotechnology Thu, 08 Oct 2009 12:00:02 EST news174219683 (PhysOrg.com) -- Small pieces of nucleic acid known as short interfering RNAs, or siRNAs, can turn off the production of specific proteins, a property that makes them one of the more promising new classes of anticancer drugs in development. Indeed, at least two siRNA-based anticancer therapies, both delivered to tumors in nanoparticles, have begun human clinical trials. http://www.physorg.com/news172951531.html Nanotechnology Wed, 23 Sep 2009 19:06:33 EST news172951531 An innovative drug-delivery system - nanoparticles encapsulating nitric oxide or prescription drugs - shows promise for topical treatment of erectile dysfunction (ED), according to a new study by scientists at Albert Einstein College of Medicine of Yeshiva University. http://www.physorg.com/news172562185.html Nanotechnology Sat, 19 Sep 2009 06:57:39 EST news172562185 (PhysOrg.com) -- The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is. http://www.physorg.com/news172072324.html Nanotechnology Sun, 13 Sep 2009 14:52:37 EST news172072324 (PhysOrg.com) -- Scientists at UC Santa Barbara have discovered a potential new drug delivery system. The finding is a biological mechanism for delivery of nanoparticles into tissue. The results are published in this week's Proceedings of the National Academy of Sciences. http://www.physorg.com/news170419576.html Medicine & Health Tue, 25 Aug 2009 11:46:57 EST news170419576 For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug must also spare healthy cells, and - ideally - its effects will be reversible, to cut short any potentially dangerous side effects. http://www.physorg.com/news168774413.html Chemistry Thu, 06 Aug 2009 11:00:03 EST news168774413 Ever since the 1966 Hollywood movie, doctors have imagined a real-life Fantastic Voyage -- a medical vehicle shrunk small enough to "submarine" in and fix faulty cells in the body. Thanks to new research by Tel Aviv University scientists, that reality may be only three years away. http://www.physorg.com/news151256253.html Nanotechnology Thu, 15 Jan 2009 15:37:33 EST news151256253 (PhysOrg.com) -- Using tiny gold particles and infrared light, MIT researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion. http://www.physorg.com/news149860678.html Nanotechnology Tue, 30 Dec 2008 11:57:58 EST news149860678
