MARTINSRIED, Germany, May 14 -- Researchers at the Max Planck Institute for Biochemistry have developed a microscope to identify material composition on a nanoscale using infrared (IR) vibrational absorption and a scanning metal tip. The scientists describe their findings in a letter appearing in this month's issue of Nature. In the experiment, the metal tip approaches a polymer film composed of different compounds and records the surface topography in standard atomic force microscope manner. An IR beam simultaneously illuminates the metal tip, which acts as an antenna and concentrates the...Read full article
