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.

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.
