Dendrites: Unique Heterogeneous Silver–Copper Dendrites with a Trace Amount of Uniformly Distributed Elemental Cu and Their Enhanced SERS Properties (Small 7/2011)

The frontispiece shows unique heterogeneous Ag–Cu dendrites with a trace amount of uniformly distributed elemental Cu. They are grown from a Cu foil/plate by a galvanic displacement reaction between an aqueous AgNO3 solution and the Cu substrate at room temperature. Owing to their unique dendritic nanostructure and the homogeneous distribution of elemental Cu, the dendrites are capable of significantly more enhancement in surface-enhanced Raman spectroscopy (SERS) compared to pure Ag dendrites, making it possible to further manipulate the SERS property of Ag nanostructures.

Huang, S.-H. Yu, and co-workers, beginning on page 857.
