SUBSTRATE FOR SURFACE-ENHANCED RAMAN SPECTROSCOPY AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2015/041442

A1

The present invention relates to a substrate for surface-enhanced Raman spectroscopy allowing surface-enhanced Raman signals to be notably improved, even in cases of long-term storage, by producing the substrate so that metal nanoparticles thereon are distanced several nanometers apart, and to a method for producing the substrate for surface-enhanced Raman spectroscopy at a large scale with simple equipment and at a low production cost. The substrate for surface-enhanced Raman spectroscopy, comprising metal nanoparicles thereon spaced several nanometers apart, can be manufactured at a large scale with simple equipment and at a low production cost. Additionally, as the distance between the metal nanoparticles can be reproducibly produced to be several nanometers, the Raman signals can be notably improved, and even in the case of long-term storage, the improved Raman signals can be sustained at a high level.
