New Antimicrobial Paint Kills Bacteria, Viruses on Contact

Scientists at the University of Nottingham have developed a new antimicrobial paint that kills a wide range of harmful bacteria and viruses, including drug-resistant strains like MRSA, influenza, and COVID-19, upon contact. The paint incorporates chlorhexidine, a disinfectant commonly used in dental and surgical settings, into a resin that activates its bacteria-killing properties once dry. Trials have shown the coating is effective on hard, non-porous surfaces such as plastics and metals, making it suitable for use in hospitals, public transport, and aerospace environments where surface-borne infections are a persistent risk. The technology aims to limit the spread of dangerous pathogens and address the growing challenge of antibiotic resistance by reducing microbial reservoirs on frequently touched surfaces. Researchers emphasize the paint's ease of application, cost-effectiveness, and its ability to maintain efficacy without leaching or environmental spread. The findings, published in Scientific Reports, suggest this innovation could significantly improve infection control in a variety of settings.
