Portable Measurement System Based on Raman Spectroscopy

Abstract:

In this paper, the portable Raman spectroscopy measurement system is presented. The measurement system can detect the Raman spectrum of objects using the advanced technique called Shell-isolated Nanoparticle Enhanced Raman Spectroscopy (SHINERS). This technique used gold nanoparticles coated with a thin, uniform, fully enclosed and optically transparent shell of silica or alumina so that the gold core generates a large surface enhancement and the shell controls the distance of the core from the surface to be detected. Based on this technique, the measurement system is designed including three modules, optical module, mechanical module and electrical control module. This Raman spectroscopy measurement system is portable, and can be used to the inspection of food safety, drugs, explosives and environment pollutants.
