Microbial synthesis of silver nanoparticles and determination of their antimicrobial properties

AgNPs were obtained through a biological method that is easy, low-cost, and environmentally friendly. The filtrates and extracts of Cladosporium cladosporioides were used for the production of silver nanoparticles. Initially, fungal filtrates and extracts were obtained and utilized in nanoparticle production. The first indication of nanoparticle production was the color change resulting from the surface plasmon resonance of the metallic nanoparticles and the characteristic absorption band. Subsequently, the characterization of the nanoparticles was performed, and their antimicrobial properties were tested. The biosynthesis of silver nanoparticles with antimicrobial effects using Cladosporium cladosporioides was characterized by analytical methods such as SEM (Scanning Electron Microscopy) and EDAX (Energy Dispersive X-ray Spectroscopy).
