Antibacterial Coatings

Research and Practice of Colloids in Antibacterial Coatings

The small size of colloidal nanomaterials provides them with a huge surface area, high reactivity, and many special properties. They are promising candidates for antimicrobial coatings. The study found that the incorporation of inorganic/organic colloidal nanoparticles into coating materials could further exploit the properties of existing surface coatings to enhance antibacterial and antiviral properties for potential medical applications. Gold, silver, platinum, magnesium oxide, copper oxide, titanium dioxide, zirconium oxide, and zinc oxide nanoparticles can all be used to create antimicrobial coatings. Fig.2 shows a possible mechanism by which colloidal nanoparticles prevent bacterial adhesion, eliminate pre-formed biofilms, and inhibit microbial colonization. In conclusion, colloidal nanomaterials have broad antibacterial prospects.
