Abstract

This is the first report of SERS switching ‘on and off’ using laser induced plasmonic heating of poly(N-isopropylacrylamide) (PNIPAM) coated hollow gold nanoshells (HGNs). The degree of Raman enhancement for these thermosensitive SERS nanotags was controlled by plasmonic tuning of the properties of the HGNs.
