ABSTRACT

There is an increasing need to develop high-yield, low cost, non-toxic and eco-friendly procedures for the synthesis of nanoparticles. Silver nanoparticles (AgNPs) synthesized through bio-green method has been reported to have biomedical applications to control pathogenic microbes as it is cost effective compared to commonly used methods. In the present study AgNPs were synthesized from aqueous silver nitrate through a simple and eco-friendly route using leaf broth of Malva parviflora, which acted as a reductant and stabilizer simultaneously. 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. The synthesized AgNPs were characterized by UV?Vis spectrophotometer analysis. The expected reaction mechanism in the formation of AgNPs is also reported. This process of synthesis creates new opportunities in process development for the synthesis of AgNPs
