Latest News on Raman Spectrometry now reaches the single molecule level, publised in Nature 06 June 2013

Chemical mapping of a single molecule by plasmon-enhanced Raman scattering was accomplished by an international team of researchers from China, Spain, and Sweden:
Hefei National Laboratory for Physical Sciences at the Microscale, University of Science and Technology of China, Material Physics Center CSIC-UPV/EHU and Donostia International Physics Center DIPC,  Spain,Theoretical Chemistry and Biology, School of Biotechnology, Royal Institute of Technology, Sweden.
Let me underline the scientific approach to ethics and probity as :

Figure 1.   Schematic drawing of our home-built experimental setup.
This setup is composed of four sub-systems: 1.  a laser source for light excitation, a dark-box for optical filtering and alignment, 2. low-temperature ultrahigh-vacuum (UHV) scanning tunneling microscope (STM) for sample preparation and characterization with 3. a built-in lens for both light excitation and collection, and 4.  a spectrometer equipped with a highly sensitive CCD detector for Raman spectral measurements.
