Methods The present study involved the synthesis of gold nanoparticles using a sodium cholate, as both reducing and capping agent and characterization by UVVisible spectroscopy and High ResolutionTransmission Electron Microscopy (HRTEM). The antibacterial activity on significant bacterial species was evaluated by micro broth dilution method. The mechanism for antibacterial action of the gold nanoparticles were studied by reactive oxygen species (ROS) generation that causes oxidative stress to… Expand

Antibacterial effect of gold nanoparticles against Corynebacterium pseudotuberculosis
Gold nanoparticles penetrated the thick wall of C. psudotuberculosis and accumulated as intracellular agglomerates and laser light enhanced the antimicrobial activity of gold nanoparticles by at least one fold due to its photo thermal combined effect. Expand
Sericin-functionalized GNPs potentiate the synergistic effect of levofloxacin and balofloxacin against MDR bacteria.
The potential role of technologies based on gold nanoparticles (GNPs) has been evaluated and the antibacterial action of SrGNPs and their bioconjugated counterparts comprising Levo, Balo, and Levo/Balo were examined against normal and multi-drug resistant (MDR) strains of E. coli and S. aureus.
