摘要：
Ag-Cu dendrites are grown from Cu foil/plate by a galvanic displacement reaction between AgNO3 aqueous solution and the Cu substrate at room temperature. The dendrites show increased surface-enhanced Raman spectroscopy (SERS) enhancement capability for the detection of organic dye molecules. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
