Silver-nano biohybride material: Synthesis, characterization and application in water purification

► Green silver nanoparticles (AgNPs) have been synthesized on the surface of Rhizopus oryzae. ► The obtained AgNPs are highly monodisperse and spherical having ∼15 nm size. ► The synthesized silver nano-biohybride have been employed for purification of water containing pesticides and microorganisms. ► AgNPs on silver nano-biohybride strongly adsorb organophosphorous pesticides due to soft-soft interaction. ► Rupture of bacterial cell wall occurred after interaction with silver nano-biohybride material.
