Facile Synthesis of Highly Uniform Selenium Nanoparticles with Antibacterial Activity on Bacillus Subtilis

Abstract
In the light of diverse applications of Selenium nanoparticles in biomedical applications, a facile procedure has been developed to synthesize highly stable, and monodisperse nanoparticles with Polysorbate 20 at room temperature. Transmission electron microscopy analysis revealed that the Selenium nanoparticles (Se NPs) were spherical in shape with uniform size of 43 nm. The antibacterial activity of Se NPs was investigated against bacillus subtilis as a model gram-positive bacteria which showed notable antibacterial activity. Results of this investigation suggest utilization of Se NPs in the next generation of nanohybrid systems with promising antibacterial efficiency.
