Antibacterial activity and mechanism of action of zinc

Mechanism of action. Zinc has three primary biological roles: catalytic, structural, and regulatory. The catalytic and structural role of zinc is well established, and there are various noteworthy reviews on these functions Mechanism of action has been ascribed to the activation of zinc oxide nanoparticles by light, which penetrate the bacterial cell wall via diffusion. It has been confirmed from SEM and TEM images of the bacterial cells that zinc oxide nanoparticles disintegrate the cell membrane and accumulate in the cytoplasm where they interact with biomolecules causing cell apoptosis leading to cell death Mechanism of Action. Miconazole inhibits the biosynthesis of ergosterol, damaging the fungal cell wall membrane. Zinc oxide is a mild astringent with weak antiseptic properties.
