Size controlled, time-efficient biosynthesis of silver nanoparticles from Pleurotus florida using ultra-violet, visible range, and microwave radiations

Monodisperse silver nanoparticles (AgNPs) were synthesized from cell free extracts of edible fungus Pleurotus florida by different electro-magnetic radiations, microwave, visible light and ultra-violet rays. The UV–vis spectroscopy of these nano-silver sols indicated the absorption maxima in 425–500 nm range. Synthesized nano-Ag sols had near spherical particles with nano-scale dimensions embedded in a matrix. Microwave irradiation led to...
