Characterization of SERS active substrate. (a) and (b) are SEM images of as-prepared SiNWs array. (c) and (d) are TEM and HRTEM images of AgNPs coated SiNWs.
Raman spectra of mIgG, gamIgG and their corresponding controls.
SERS spectra of mIgG, gamIgG and their immunocomplex.
Schematic illustration of SERS system for immune reaction. The mIgG, gamIgG, and their immunocomplex occupy different cavities (ideal status for easy understanding).
Proposed Assignment of the Raman peaks for mIgG, gamIgG, and their immunocomplexes.
