A Comparative Study of Galvanic Replacement Reactions Involving Ag Nanocubes and AuCl2− or AuCl4−

Galvanic replacement of Ag nanocubes with AuCl2− and AuCl4− results in morphological, compositional, and spectral differences that provide insight into the reaction mechanism by which hollow/porous gold nanostructures can be prepared for biomedical applications.
