The spread and spread of harmful bacteria is the source of many major diseases, which in turn pose a serious threat to human health. Therefore, antibacterial materials have gradually entered people's field of vision, have been highly valued, and have become a key research direction in various fields such as medical treatment, chemical building materials, and food packaging. Alfa Chemistry has done a lot of research in the field of antibacterial coatings. We have a variety of colloid and surface treatment technologies, which can provide solutions for the development of new antibacterial coatings that are environmentally friendly, stable, efficient, and durable.

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.
