Excess amounts of a naturally fluorescent molecule found in all living cells could serve as a natural biomarker for cancer, according to bioengineers. http://www.physorg.com/news157889633.html Chemistry Thu, 02 Apr 2009 11:14:24 EST news157889633 (PhysOrg.com) -- A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free mapping of local conductivity in strain-engineered electronic devices (Nature Nanotechnology, advanced online publication, 11 Jan. 2009). http://www.physorg.com/news151930864.html Nanotechnology Fri, 23 Jan 2009 11:01:37 EST news151930864 (PhysOrg.com) -- A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors.
