10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 1 2014 (January - March) A simple method for synthesis of biologically stabilized silver nanoparticles was developed using the seed extract of lessThan i greaterThan Argyeria nervosa lessThan /i greaterThan . The nanoparticles synthesized using lessThan i greaterThan A. nervosa lessThan /i greaterThan were characterized by UV-Vis spectrophotometry, X-Ray Diffraction, SEM- EDS and FTIR. The antibacterial and antifungal activity of silver nanoparticles was assessed against lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan , lessThan i greaterThan Bacillus subtilis lessThan /i greaterThan , lessThan i greaterThan Aspergillus niger lessThan /i greaterThan , lessThan i greaterThan Escherichia coli lessThan /i greaterThan and lessThan i greaterThan Pichia lessThan /i greaterThan lessThan i greaterThan pastoris lessThan /i greaterThan . The silver nanoparticles synthesized thus demonstrated potent antagonistic activity against bacteria and fungi which possess potential applications in medicine and pharmaceutical fields.
