Simplifying Pigment Detective Work
When conservation scientists examine the pigment composition of great masterpieces, they use techniques that produce minimal damage to the paintings. Now one of these sensitive techniques may have gotten one step simpler.
Researchers led by Kristin Wustholz, a chemist at the College of William & Mary, made the improvement to a protocol called surface-enhanced Raman scattering (SERS). The method pinpoints the chemical make-up of pigment from just a single microscopic particle of the . . .
