Abstract:
SERS you right: The plasmon heating of gold nanoshells is exploited to yield the local conversion of amorphous TiO(2) into anatase on the surface of polymeric colloidal crystals (see scheme). The resulting Au/TiO(2) spots are active substrates for surface-enhanced Raman spectroscopy and allow surface reactions and processes to be followed directly on-site.
