Antibacterial, Antifungal, Anti-Tumor and Larvicidal Activity of Platinum Nanoparticles Synthesized from Photosynthetic Purple Non Sulphur Bacteria

Abstract

Nanotechnology has received a lot of attention, and nanomaterials have a wide range of applications in every field of life. Researchers are constantly working on the methodology for making nanoparticles (NPs). The NPs were successfully biogenically prepared and used in a variety of fields, including medicine, biosensors, electrochemistry, biomedicine, water treatment, electronics, photo-electronics, and catalysis. Platinum nanoparticles (PtNPs) synthesised from purple non-sulphur bacteria were tested for antibacterial, antifungal, anti-tumor, and larvicidal activity in this study. The antibacterial activity of each tested PtNP was assessed using the zone of inhibition against four different groups of bacteria. The antifungal activity of biologically synthesised platinum nanoparticles was tested on Potato dextrose agar plates using the agar well diffusion method. In-vitro cytotoxicity effect of PtNPs compound was studied against HeLa cell and DU145 (Human Prostate cancer cells) cells lines at different concentrations. The results are presented and discussed in this communication
