Synthesis and characterization of PtNPs using tangeretin. (A) Absorption spectra of tangeretin-mediated PtNP synthesis; the absorption spectra of PtNPs exhibited a strong broad peak at 304 nm, and observation of such a band is assigned to surface plasmon resonance of the particles. (B) X-ray diffraction patterns of PtNPs; the broad diffraction peaks of the XRD pattern at 2θ = 40.0, 47.6, 67.5, 81.8, and 88.6° were observed (C) FTIR spectra of PtNPs; (D) size distribution analysis of PtNPs by DLS; (E) TEM micrograph images of PtNPs; several fields were photographed and used to determine the diameter of AgNPs using TEM; and (F) corresponding particle size distribution histograms. At least three independent experiments were performed obtaining reproducible results and data from representative experiments are shown.
