Silver nanospheres: Biosynthesis using resurrection plant extract, characterization and in vitro antibacterial activity

This work aims to synthesis silver nanoparticles using the extract of resurrection plant as a reducing agent. The resulting product of silver nanoparticles was characterized using XRD and TEM and the results show that there is a pure silver nanoparticles was produced with sphere-like nano silver of 30-50 nm. Furthermore, the as-prepared nanosilver was used as potential anti-bacterial against two Gram positive bacteria; s. aureus and s. epidermidis. The results prove that the as-prepared silver nanosphere is able to inhibit the bacteria growth with maximum inhibition zone diameter of 15 mm (s. aureus) and 20 mm (s. epidermidis) using 160 mg/ml concentration from Ag nanospheres.
