Anti-bacterial Studies of Silver Nanoparticles

TL;DR

This study explores how silver nanoparticles synthesized via electrolysis exhibit enhanced antibacterial effects, especially against Gram-negative bacteria, with lattice constant modifications influencing their efficacy.

Contribution

It introduces a novel electrolysis synthesis method that increases antibacterial activity of silver nanoparticles by applying electrical power.

Findings

Electrolysis-synthesized silver nanoparticles show higher activity against Gram-negative bacteria.

Applying electrical power during synthesis enhances antibacterial effectiveness.

Changes in lattice constant correlate with increased antibacterial activity.

Abstract

We discuss about the antibacterial activities of Silver nanoparticles and compare them on both Gram negative and Gram positive bacteria in this investigation. The activities of Silver nanoparticles synthesized by electrolysis method are more in Gram (-) than Gram (+) bacteria. First time, we increase its antibacterial activities by using electrical power while on electrolysis synthesis and it is confirmed from its more antibacterial activities (For Escherichia coli bacteria). We investigate the changes of inner unit cell Lattice constant of Silver nanoparticles prepared in two different methods and its effects on antibacterial activities. We note that slight change of the lattice constant results in the enhancement of its antibacterial activities.
