Scientists from the University of Nottingham's School of Pharmacy, together with Indestructible Paint, have developed an antimicrobial paint capable of destroying dangerous bacteria and viruses, including resistant strains of MRSA (Staphylococcus aureus bacteria, which has become resistant to many antibiotics), influenza and the COVID-19 coronavirus. The results of the work are published in the journal Scientific Reports.
The new coating is based on a resin with the addition of chlorhexidine, an antiseptic widely used by dentists and surgeons to fight infections. When applied to plastic or hard non-porous surfaces, the paint becomes active after drying and begins to destroy pathogens.
"It is extremely exciting to see how this research is applied in practice. Our paint does not leach out when touched and does not pollute the environment. After drying, the surface becomes active and completely free of bacteria," said Dr. Felicity de Kogan, Associate Professor at the Department of Pharmacy of Biological Medicines.
Antimicrobial paint is particularly promising for use in hospitals, transportation, and public facilities, where pathogens often survive even after thorough cleaning. For example, it is known that on the surface of hospital beds, toilet seats, and tables on airplanes, bacteria can persist for weeks or even months, increasing the risk of human infection.

The paint solves another major problem - preventing the spread of antibiotic resistance genes. Even with regular disinfection, bacteria can exchange genes among themselves that make them immune to drugs. The new development, according to the researchers, will help stop this process.
"Paint is a versatile, cheap and durable way to protect surfaces. The creation of antimicrobial coatings is important to combat the threat of antimicrobial resistance, especially in medical institutions," added Felicity de Kogan.
Indestructible Paint, a company specializing in the development of industrial coatings for aviation, railway and other industries, sees great prospects in this technology.
The development of antimicrobial paint is of particular importance against the background of the global fight against infections and the growing resistance of microbes to antibiotics. The project shows how modern materials can become an effective weapon in the fight for human health.
