Preparation and Structure of Silver- Nanoparticles Stabilized with Poly (vinyl alcohol) by electrochemical method for antimicrobial application

Afaf Sarhan


Present research was devoted to characterize the green preparation of Poly (vinyl alcohol) -Silver nanoparticles (PVA/AgNPs) by using eco-friendly method established on electrochemical process and then subjected to UV-irradiation reduction. The properties of improved PVA/AgNPs have been evaluated by some analytical techniques such as, UV–Vis spectrophotometry, Fourier transform infrared (FTIR), X-ray diffraction pattern, Atomic force microscope (AFM) and antibacterial activity.  From UV spectra, it is noticed that, surface plasmon absorption peak released at 420 nm which ensure the nanoparticles were produced. The values of direct energy gap of all samples have been determined and it decreased with increasing electrochemical time and after UV-irradiation. The FT-IR analysis of the UV- irrediated samples did not appear a considerable variation compared with the conforming analysis before UV- irradiation. Also it is verify complexation between PVA groups with Ag. Also some biological properties of the prepared PVA/AgNPs are studied, which are useful in different biomedical and pharmaceutical applications. The improved PVA/AgNPs also appeared the highest antibacterial activity via Gram-positive Staphylococcus aureus (S.aureus) and Gram-negative Escherichia coli (E. coli) and the antibacterial enhanced with increasing the NPs concentration. These data demonstrated that the synthesized NPs used in many potential applications.
