Biogenic platinum based nanoparticles: Synthesis, characterization and their applications for cell cytotoxic, antibacterial effect, and direct alcohol fuel cells

Abstract

In this study, biogenic platinum nanoparticles (Pt NPs) were obtained using the green synthesis method. The obtained Pt NPs were characterized using X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM), and the plant extract was characterized using Fourier Transform Infrared Spectroscopy (FTIR). With this characterized Pt NPs, cytotoxicity tests on MIAPaCa 2, Hela, HEK 293, Thle 2 cell lines and antibacterial activities on S. Aureus, S. Mutans, E. Coli, E. Faecalis bacterial cell lines were investigated. As a result, it was observed that biogenic Pt NPs showed a cytotoxic effect on cell lines and an antibacterial effect against a series of bacteria. At the same time, in order to show the usability of Pt NPs synthesized by the green synthesis in different areas, studies for alternative clean energy production were also carried out, and in the methanol oxidation reaction study, 5.42 mA.cm−2 anodic peak current was obtained at 0.6 V potential. This showed that nanoparticles obtained by the green synthesis method can be used in alcohol oxidation studies for alternative clean energy generation.
