We are developing thin-film-flake-dispersion gel for SERS sensing. The new gel-type porous SERS sensor is expected to be developed to collect biomarkers directly from the surface. This study aims to elucidate the difference in transport phenomena of different types of molecules based on SERS spectral intensity time change.
