Antibacterial Properties of Ag₃PO₄ Particles on Bacteriostatic Behavior of Escherichia coli

Abstract:

The aim of this work was to investigate the influences of different concentrations of Ag₃PO₄ aqueous dispersion by measuring the bacteriostatic characteristic against bacteria E. coli. The Ag₃PO₄ particles were successfully synthesized by precipitation method. Then, the morphological, structural and chemical compositional analyses were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), respectively. All these analyses confirmed the formation of Ag₃PO₄ particles with the shape of nearly spherical with a size of 100 – 700 nm. Meanwhile, Kirby-Bauer disk diffusion susceptibility test was chosen to determine the sensitivity of E. coli to antibacterial compounds in Ag₃PO₄ particles. The results showed that the antibacterial ability was significantly improved by increasing the concentration of Ag₃PO₄ aqueous dispersion, and the best concentration was 600 mg /mL. This study suggested that Ag₃PO₄ particles can be exploited as an effective candidate for antibacterial agents.
