摘要：

The fabrication of supercrystals of standing core-shell gold-silver nanorods stabilized by gemini surfactants provides SERS substrates with high optical activity, large homogenous sensing areas, and the potential to maximize the SERS signal with respect to their gold nanorod supercrystal counterparts. © 2013 WILEY-VCH Verlag GmbH & Co.
