Oxidative stress generated due to photocatalytic activity of biosynthesized selenium nanoparticles triggers cytoplasmic leakage leading to bacterial cell death

Abstract

(MTCC 443) and anti-biofilm activity against biofilm forming bacteria. The mechanism behind antimicrobial activity of biosynthesized SeNPs was explored by evaluating the amount of reactive oxygen species (ROS) generated at SeNPs interface due to photocatalytic activity. The experimental data obtained altogether concluded that, the ROS generated at SeNPs interface put stress on bacterial cell membrane causing leakage of cytoplasmic contents, leading to bacterial cell death.
