The aim of this study was to screen biogenic platinum nanoparticles for antifungal properties by a combination of in vitro methods. During this study, marine actinobacteria (Streptomyces sp. mediated biogenic platinum nanoparticles were screened for their antifungal activity against Aspergillus flavus, A. niger, Penicillium sp., Candida albicans and C. tropicalis. Biologically synthesized platinum nanoparticles exhibited broad spectrum antifungal activity against test organisms. | Antifungal activity of biogenic platinum nanoparticles An in vitro study
