3D plasmonic nanostar structures for recyclable SERS applications

摘要

Nanofabrication of metallic nanostructuresanoparticles enables the detection of analyte molecules at ultra-low concentrations with the aid of plasmon induced hot-spots. The high fabrication cost and large fabrication time of nanostructures limit their usage in practical applications. Here we present a cost effective approach to recycle the SERS substrates.
