Keywords: surface-enhanced Raman spectroscopy (SERS), superresolution imaging

Superresolution imaging by single-molecule surface-enhanced Raman spectroscopy (SERS) shows that SERS-active sites called "hot spots" on metal nanoparticles may be larger than previously thought. Katherine A. Willets, an assistant chemistry professor at the University of Texas, Austin, presented her group's results at the American Chemical Society meeting in Boston and in a recent paper (Nano Lett., DOI: 10.1021/nl102559d). Their findings could help scientists . . .
