Description
Summary:An oxidative polymerization approach was used to create polyaniline (PANI) and Fe2O3 /PANI nanoparticle combination. Various characterization approaches were used to investigate the structural, morphological, and Fe2O3 /PANI nanoparticle structures. The findings support the synthesis of polycrystalline nanoparticle PANI and Fe2O3 /PANI spherical nanoparticle composites. Gram-positive bacteria are tested for antibacterial activity. Various quantities of Nanoparticles of PANI and Fe2O3 /PANI nanoparticle composites were used to test Staph-aureus and gram-negative bacteria, E-coli, and candida species. PANI has antibacterial properties against all microorganisms tested. Fe2O3 /PANI nanoparticle composites, on the other hand, have higher antibacterial activity, as evidenced by the zone of inhibition. Bacterial inhibition zones are in S. aureus (positive), and E. coli are in good functioning order. With increasing concentrations of Fe2O3 /PANI nanoparticle composites, the inhibition zones of all bacteria are larger. Finally, the antimicrobial activity of Fe2O3 /PANI nanoparticle composite is characterized using a simplified mechanism based on electrostatic attraction. In this paper, a conductive polymer doped with iron nanoparticles was fabricated for the aim of testing it in the field of bacterial resistance.
