| Research Abstract |
A molecular analysis system at liquid/solid interface utilizing Surface-enhanced Raman Scattering (SERS) was developed using two kinds of plasmonic sensors, a concentric-circled groove type and transparent substrate with nano-particles made of Au, Ag, and Cu. For application examples, adsorption behavior of hydrazine and hypophosphate as a reducing agent at the Cu/liquid interface in the atomistic level. The decomposition reaction with an electric field for Janus Green B (JGB) as a deposition inhibitor was observed at Au/liquid interface. Molecular structure of lubricant molecules on a Diamond-Like Carbon (DLC) film for hard disk media was successfully measured in the depth resolution of 0.1 nm.
