(PhysOrg.com) -- A portable instrument manufactured by Nanosphere Inc. and recently approved by the FDA, can detect genetic variations in blood that alter the effectiveness of some drugs. http://www.physorg.com/news178991057.html Nanotechnology Wed, 02 Dec 2009 16:20:03 EST news178991057 (PhysOrg.com) -- Mention of arsenic poisoning usually brings to mind underhanded murder. However, the danger of arsenic poisoning from contaminated drinking water is far greater. Low concentrations of arsenic are found in nearly all soils and thus also in ground water. About 140 million people worldwide possibly drink water that contains arsenic concentrations above the WHO-recommended limit of 10 ppb (parts per billion). http://www.physorg.com/news178347619.html Nanotechnology Wed, 25 Nov 2009 05:02:58 EST news178347619 Vibrations in nanostructures offer applications in molecular-scale biological sensing and ultrasensitive mass detection. To approach single-atom sensing, it is necessary to reduce the dimensions of the structures to the nanometer scale while preserving long-lived vibrations. http://www.physorg.com/news177870451.html Nanotechnology Thu, 19 Nov 2009 16:28:18 EST news177870451 (PhysOrg.com) -- Cisplatin is one of the most powerful and effective drugs for treating a wide variety of cancers, but serious side effects ultimately limit the drug's use and effectiveness. Now, however, researchers have developed a nanoparticulate formulation of cisplatin that may be able to eliminate or reduce platinum-associated toxicity while boosting cisplatin's tumor-killing activity. http://www.physorg.com/news176060990.html Nanotechnology Thu, 29 Oct 2009 18:50:19 EST news176060990 Scientists in Israel have devised a portable breath tester that detects lung cancer with 86 percent accuracy, according to a study released Sunday. http://www.physorg.com/news170864052.html Nanotechnology Sun, 30 Aug 2009 15:50:01 EST news170864052 (PhysOrg.com) -- Those who like to watch spy movies like `Mission Impossible` are familiar with the self-destructing messages that inform the secret agents of the details of their mission and then dissolve in a puff of smoke. In the real world, there is serious interest in materials that don't exactly destroy themselves, but that store texts or images for a predetermined amount of time. http://www.physorg.com/news170495261.html Nanotechnology Wed, 26 Aug 2009 08:48:33 EST news170495261 Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package. http://www.physorg.com/news167933174.html Nanotechnology Mon, 27 Jul 2009 17:17:04 EST news167933174 By studying gold nanoparticles with highly uniform sizes and shapes, scientists now understand how they lose energy, a key step towards producing nanoscale detectors for weighing any single atom. http://www.physorg.com/news167912822.html Nanotechnology Mon, 27 Jul 2009 11:27:29 EST news167912822 An over-the-counter prostate cancer test kit could be coming to a pharmacy near you, thanks to the collaborative work of a University of Central Florida chemist and M.D. Anderson Cancer Center Orlando researchers. http://www.physorg.com/news163255080.html Medicine & Health Wed, 03 Jun 2009 13:38:36 EST news163255080 (PhysOrg.com) -- It has long been known that heat is an effective weapon against tumor cells. However, it's difficult to heat patients' tumors without damaging nearby tissues. http://www.physorg.com/news160665499.html Nanotechnology Mon, 04 May 2009 14:18:53 EST news160665499 (PhysOrg.com) -- Materials containing bimetallic nanoparticles are attractive in vast technological fields because of their unique catalytic, electronic, and magnetic properties. One of the most promising of the bunch is made from palladium and gold, an alloy that could be used in a wide variety of catalytic activities including the water-gas shift reaction and the oxidation of carbon dioxide - both important steps in alternative energy applications like fuel cells. http://www.physorg.com/news156446716.html Nanotechnology Mon, 16 Mar 2009 18:25:44 EST news156446716 (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
