A technology to generate microbubbles by focusing near-infrared laser light onto a substrate with plasmonic properties, enabling the collection and analysis of low-concentration nanomaterials dispersed in water, was investigated. In this presentation, polystyrene nanoparticles were dispersed in water, and microbubbles were generated to accumulate the nanoparticles on a silver nanostructure surface. The distribution and quantity of the accumulated particles were analyzed using fluorescence imaging, and spectroscopic data analysis to detect the polystyrene particles based on surface-enhanced Raman scattering (SERS) was studied.
