Green Synthesis and optimization of monodisperse silver nano particles using Ocimum santum aqeous leaf extract

The current study proposes a simple, inexpensive, and eco-friendly method of green synthesis of silver nanoparticles using the leaf extract of Ocimum sanctum. The presence of a multitude of chemicals in Tulsi, especially phenolic compounds, contributes to effective reduction of silver ions and stabilization of synthesized nanoparticles. The produced AgNPs were confirmed through visual inspection, distinct UV-Vis SPR peak, and SEM which demonstrated uniformity and polytypism with sizes in the range of 10-50 nm. The results indicate the applicability of the synthesized Ocimum sanctum AgNPs in nanobiotech and pharmaceuticals thus paving the way for environmentally-friendly protocol in industrial-scale synthesis of nanoparticles. However, the studies on extraction, characterization and evaluation of toxicity of active components must be carried out. From the technology point of view, these silver nanoparticles have a significant number of applications in medicine.
