Abstract

Surface-enhanced Raman spectroscopy (SERS) relies on adsorbing target molecules onto metal nanostructures where the light can resonantly couple with localised surface plasmon resonances. These plasmons can be tuned by changing the nanostructure size, shape, spacing and composition, but this is a com...
