Preparation, characterization, and antimicrobial activity of polyaniline and fe2o3-polyaniline composite nanoparticle

Abstract EN

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.
