Abstract
Nanoparticles are being increasingly used in day-to-day life. Therefore, concerns have been raised regarding their interactions with the surrounding environment. This study focused on a simple green method for synthesizing silver nanoparticles (Ag-NPs) in an autoclave at 15 psi (103 kPa) and 121°C. An aqueous solution of AgNO3 as a precursor of Ag-NPs and gelatin (type B) reducing and/or stabilizing (capping) agent were used. The effect of various AgNO3 concentrations of certain gelatin concentration and various gelatin concentrations at constant AgNO3 concentration, and autoclaving time, was studied. UV-Vis spectra ascribed that the presence of localized surface plasmon resonance (SPR) of the synthesized Ag-NPs. TEM images and the selected area of electron diffraction confirmed, the formation of Ag-NPs with a diameter of approximately 5 ±0.35 nm. Furthermore, FT-IR revealed that a gelatin polymer matrix stabilized the synthesized Ag-NPs. The Well diffusion assay was used to test the effect of Ag-NPs on six clinical bacterial isolates, where Gram positive bacteria were more susceptible to Ag-NPs than Gram negative bacteria. Therefore, Ag-NPs capped by gelatin have remarkable potential effect as an antibacterial agent, and they ...Continue Reading
