Using light-force to study single molecules

Scientists at EPFL show how to amplify the sensitivity and resolution of Raman scattering

25-Nov-2015

When it comes to studying single molecules, scientists use a powerful technique called "surface-enhanced Raman scattering" (SERS). An extremely sensitive tool, SERS detects the vibrations within the atoms of the illuminated molecule as a change in light color. But the sensitivity of SERS is ...
