Green Synthesis of Silver Nanoparticles Using Catharanthus Roseus

A green rapid biogenic synthesis of silver nanoparticles (AgNPs) using Catharanthus roseus leaf extract. Synthesized nanoparticles were characterized using UV-Visible, FTIR and XRD. The reduction of silver ions to AgNPs using C. roseus extract was completed within 240 mins. The formation of AgNPs was confirmed by using Surface Plasmon Resonance (SPR) at 413 nm using UV-Vis Spectrophotometer. From the morphological studies, revealed the spherical shape of the particles with sizes ranging from 16-35 nm and EDX spectrum confirmed the presence of silver along with other elements in the plants metabolite. The extracellular AgNPs synthesis by aqueous leaf extract demonstrates ultra-fast, simple and inexpensive method comparable to other methods. The antioxidant assay of the synthesized AgNPs indicated that they have a strong antioxidant property as compared to the control. Since these compounds are also safe to use and discharged into the environment, the green AgNPs could be considered as an innovative alternative approach for biomedical and nanoscience based industries.
