Enviro-Friendly Synthesis of Silver Nanoparticles Using Berberis lycium Leaf Extract and Their Antibacterial Efficacy

In the present study, an enviro-friendly synthesis of silver nanoparticles from Berberis lycium Royle leaf extract and their antibacterial efficacy against five pathogenic bacteria were investigated. This biosynthesis technique is proved to be advantageous over physical and chemical methods as no toxic chemicals are used. The structural and morphological characterization was made by UV-visible spectroscopy, scanning electron microscopy, and transmission electron microscopy. The synthesized nanoparticles were oval, rectangular, and spherical in shape, size ranges from 8 to 100 nm and exhibited an absorption peak at 458 nm. The biosynthesized silver nanoparticles have shown good antibacterial effect toward tested bacteria. It is believed that these biosynthesized silver nanoparticles can play a vital role in nano-based products in future.
