Abstract
A facile, green route method has been developed for the synthesis of silver nanoparticles. A single step ecofriendly approach has been employed usinga natural polymer, okara juice (Abelmoschus esculentus) as a binding agent, along with mandelic acid as reducing agent. UV-visible absorption spectrum recorded for the solution has shown significant bands in the range of 200nm to 600nm.The morphology of silver nanoparticles was observed by FE-SEM and Transmission electron microscopy (TEM). The prepared silver nanoparticles showed unique anti-microbial activity against gram-negative bacteria, such as Escherichia coli, and gram-positive bacteria, such as Staphylococcus aureus.
