Antimicrobial coatings are materials that are applied to surfaces to inhibit the growth of microorganisms, such as bacteria, viruses, and fungi. These coatings are often used in healthcare settings, food processing facilities, and other areas where cleanliness and hygiene are important. Antimicrobial coatings can help prevent the spread of infections and diseases by reducing the number of harmful pathogens on surfaces. They can also help to prolong the life of materials by preventing the growth of mold and mildew. Research in this area focuses on developing new antimicrobial coatings that are effective, long-lasting, and safe for use in various applications.
