(PhysOrg.com) -- One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering. http://www.physorg.com/news179520620.html Nanotechnology Tue, 08 Dec 2009 19:00:01 EST news179520620 Researchers at The Scripps Research Institute have found, crystallized, and biologically characterized a poorly defined component of a key molecular complex that helps people to avoid cancer, but that also helps cancer cells resist chemotherapy. http://www.physorg.com/news173618253.html Biology Thu, 01 Oct 2009 12:18:36 EST news173618253 Screening a chemical library of 200,000 compounds, researchers at UT Southwestern Medical Center have identified two new classes that can be used to study and possibly manipulate a cellular pathway involved in many types of cancer and degenerative diseases. http://www.physorg.com/news152540976.html Biology Fri, 30 Jan 2009 12:30:34 EST news152540976 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
