SURFACE-ENHANCED RAMAN SCATTERING NANO PARTICLE AND ANALYSIS SYSTEM USING THE SAME

摘要

PURPOSE: A surface-enhanced raman scattering nanoparticles and an analysis system using the same are provided to enable minute analysis of chemical or biological substances. CONSTITUTION: A surface-enhanced raman scattering(SERS) particles contains metal nanoparticles, one or more organic compounds, and an analyte. The organic compound has a functional group which changes aggregation of the ramen scattering particles. The functional group is -SH, -CN, -COOH, -POOH, or mixture thereof. The metal nanoparticles and organic compounds are denoted by chemical formula 1. The particles are soluble and the concentration of the analyte is more than 100pM.
