Antibiofilm and Antimicrobial Activities of Silver Boron Nanoparticles Synthesized by PVP Polymer and Gamma Rays Against Urinary Tract Pathogens.

In the present study gamma-rays induced eco-friendly synthesis of silver boron nanoparticles (AgB NPs) using PVP polymer as a stabilizing agent. Antimicrobial and antibiofilm activities of AgB NPs were examined against multidrug-resistant microbes that cause urinary tract infection (UTI). AgB NPs were characterized by UV–Vis, SEM/mapping images, EDX, HRTM, DLS, FTIR and XRD analysis. A proposed reaction mechanism was investigated. Data obtained from results indicated that AgB NPs production was dependent on silver nitrate and boric acid concentrations. HRTEM image displayed the anisotropic AgB NPs with a diameter of 85.25 nm. FTIR spectrum data shows that there is a continuous reduction of ions due to the oxidation of PVP. Ring opening was assigned by N–H bond formation. AgB NPs presented a great efficiency against Candida albicans (20.0 mm ZOI) followed by Escherichia coli (18.0 mm ZOI) and Staphylococcus aureus (16.0 mm ZOI). Additionally, AgB NPs were provided biofilm inhibition % as 87.0, 85.3, and 69.4% against S. aureus, E. coli, and C. albicans, respectively. Accordingly, due to AgB NPs properties such as encourages antimicrobial agent with continued-term stability; they must identify possible purposes within pharmaceutical and medical application in the UTI treatment.
