The tool, called the nanofountain probe, functions in two different ways. In one mode, the probe acts like a fountain pen with drug-coated nanodiamonds serving as the ink, allowing researchers to create devices by `writing` with it. The second mode functions as a single-cell syringe, permitting direct injection of biomolecules or chemicals into individual cells. The research was led by Horacio Dante Espinosa, Ph.D., and Dean Ho, Ph.D., and the results appear in the journal Small. http://www.physorg.com/news165512374.html Nanotechnology Mon, 29 Jun 2009 21:10:03 EST news165512374 (PhysOrg.com) -- The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials. http://www.physorg.com/news164638938.html Nanotechnology Fri, 19 Jun 2009 14:03:06 EST news164638938 Scientists have identified for the first time a mechanism by which nanoparticles cause lung damage and have demonstrated that it can be combated by blocking the process involved, taking a step toward addressing the growing concerns over the safety of nanotechnology. http://www.physorg.com/news163904073.html Nanotechnology Thu, 11 Jun 2009 01:54:54 EST news163904073 (PhysOrg.com) -- Researchers at the Commerce Department's National Institute of Standards and Technology (NIST) and Cornell University have capitalized on a process for manufacturing integrated circuits at the nanometer (billionth of a meter) level and used it to develop a method for engineering the first-ever nanoscale fluidic (nanofluidic) device with complex three-dimensional surfaces. http://www.physorg.com/news157729849.html Nanotechnology Tue, 31 Mar 2009 14:51:10 EST news157729849 Imagine flexible lighting devices manufactured by using printing techniques.
