Abstract

Biosynthesis and characterization of gold and silver nanoparticles (NPs) using biomolecules such as exopolysaccharide (EPS), cell free filtrate (CFF) and fruiting body extract (FBE) of Pleurotus ostreatus (PO) and antimicrobial potential of the biosynthesized NPs and functionalized NPs against some multidrug resistant bacteria was investigated. The silver NPs (SNPs) and gold NPs (AuNPs) biosynthesized using the biomolecules (EPS, CFF and FBE) were characterized using visual observation, UV-visible spectrophotometer, Fourier transform infrared (FTIR) and scanning electron microscope (SEM). Changes in colour from pale yellow and cloudy colour to dark brown and to purple and dark purple indicate the formation of SNPs and AuNPs. The intensity of the colour differs from CFF
