Optimization of Biosynthesis of Silver Oxide Nanoparticles and Its Anticancer Activity

Abstract

Silver oxide nanoparticle can be synthesized by chemical and biological methods. Biological synthesis has emerged as an exciting, ecofriendly approach. However, the process tends to be slow when we consider its industrial applicability. The development of reliable method for rapid synthesis of nanoparticles is one of the significant zones of interests in current nanotechnological research. In this paper, optimization of physiochemical parameters for rapid silver oxide nanoparticle synthesis using Bacillus thuringiensis SSV1 culture supernatant has been elucidated. Spherical-shaped silver oxide nanoparticles with an average particle size of 30[Formula: see text]nm were obtained. The cytotoxic effect of silver oxide nanoparticles was studied against HepG2 and Chang liver cell lines by MTT assay. These nanoparticles showed dose-dependent response on HepG2 (IC[Formula: see text]g/mL) and Chang liver cells (IC[Formula: see text]g/mL).
