Antimicrobial activity of biosynthesized Cuo/Se nanocomposite against Helicobacter pylori

Abstract

Recently, nanotechnology has been considered one of most frontiers in scientific sector, which increasingly attracts researchers’ interest due to its variable and valuable applications in all areas. The synthesis of nanoparticles represents a promising era in therapeutic research that may lead to the development of new approaches in pharmaceutical studies. Selenium nanoparticles (SeNPs) share a status of high repute owing to their remarkable therapeutic potential. Biological synthesis of environment-friendly SeNPs using plant extracts has emerged as a beneficial alternative approach to chemical synthesis. In this regard, we have synthesized biogenic PG-SeNPs using pomegranate peels aqueous extract (PPAE) as a stabilizing and reducing agent. The PG-SeNPs were evaluated for their anti-Helicobacter pylori and anti-stomach cancer potential. The PG-SeNPs were efficacious against H. pylori. The PG-SeNPs showed dose-dependent restriction of the growth of H. pylori. The anti-stomach cancer ability of the PG-SeNPs was evaluated against SNU-16 stomach cancer. As evident from the MTT results, PG-SeNPs reduced cell viability in a dose-dependent manner. Briefly, the PG-SeNPs evolved with synergistically emerging attributes that were effective against H. pylori; Moreover, the PG-SeNPs and SeNPs@CuO embody intriguing anticancer potential against stomach cancer cells.
