Study of Synergistic Effects of Antibiotics And Triangular Shaped Silver Nanoparticles, Synthesized Using UV-Light Irradiation, on S. Aureus and P. Aeruginosa

Now days, resistance of bacteria to bactericides and antibiotics has increased. Some antimicrobial agents are extremely irritant and toxic. Hence there is a need to find ways to formulate green and less toxic materials. In the present work, a study of synergistic effects of as-synthesised triangular shaped silver nanoparticles and two standard antibiotics, ampicillin and gentamycin, was studied on Staphylococcus Aureus and Pseudomonas Aeruginosa. A green route is taken to synthesise silver nanoparticles using silver oxalate as precursor; tea extract and chitin as capping and stabilizing agents respectively. A grey coloured colloidal solution of silver nanoparticles is obtained. XRD, TEM and UV-visible spectroscopy, are used tocharacterise the as-synthesised silver colloidal solution.
