Abstract

A highly SERS-active substrate was fabricated by trapping gold "nanoworms" on commercially available filter membranes providing significant enhancement of the Raman signal as a result of the remarkable electromagnetic couplings induced by the dense packing. The resultant substrate provides a simple and cost-effective porous SERS surface for use and quantitative analytical procedures.
