Silver dendrites from galvanic displacement on commercial aluminum foil as an effective SERS substrate.

Abstract

A silver galvanic displacement process on commercial aluminum foil has been carried out to produce cost-effective SERS substrates. The process is based on an extremely simple redox process where aluminum is oxidized while silver ions are reduced, yielding a final silver dendritic structure that offers a large surface area-to-volume ratio.
