Fig. 2. Photoluminescence spectra of TiO2/glass nanoparticles: (a) before and after the immobilization of gp51 on the TiO2/glass surface and after BSA deposition; (b) photoluminescence spectra of gp51/TiO2/glass based immunosensor after the interaction with analyte (anti-gp51), which is present in the aliquots at different concentrations.
