The fluorescence quenching study. (A) Fluorescence titration. The upper spectrum corresponds to the emission of Md-Lec alone and the remaining spectra depicts the decreasing fluorescence emission spectra with increase in the concentration of the PtNPs (0–100 µM) (B) Stern–Volmer plot. (C) Haemagglutination assay. C Control RBC, L Md-lec, PPt Pt-lec.
