The primary mechanisms by which anti-bacterial nanocoatings work include:
1. Release of Antimicrobial Agents: These nanocoatings can release substances like silver nanoparticles, which have strong bactericidal properties. 2. Contact Killing: Certain coatings function by killing bacteria upon contact. Materials like copper nanoparticles disrupt bacterial cell membranes when bacteria come into contact with the coated surface. 3. Photocatalytic Activity: Some nanocoatings utilize photocatalysts such as titanium dioxide nanoparticles that, when exposed to light, produce reactive oxygen species capable of destroying bacterial cells.
