ABSTRACT

A facile and eco-friendly method for the preparation of Silver nanoparticles (AgNPs) has been developed based on bioreduction of silver nitrate precursors with Coriandrum sativum leaf extract in aqueous environment. The effect of reaction time, and AgNPs formation mechanism has been investigated. The formation of AgNPs was observed by the change of color from colorless to dark brown by the addition of silver nitrate into leaves extract. It was observed that use of Coriandrum sativum leaf extract makes convenient method for the synthesis of silver nanoparticles and can reduce silver ions into silver nanoparticles within one hour of reaction time without using any harsh conditions. Silver nanoparticles so prepared were characterized by using UV?visible spectroscopy. This process of synthesis creates new opportunities in process development for the synthesis of AgNPs
