The Science Behind the Breakthrough

Researchers at the University of Nottingham have developed a groundbreaking antimicrobial paint that effectively eliminates harmful bacteria and viruses upon contact. This innovative coating incorporates chlorhexidine digluconate (CHX), a potent disinfectant commonly used in medical settings, into a resin-based formula. Once applied and dried, the paint becomes immediately active, targeting pathogens such as MRSA, influenza, and COVID-19. Importantly, it does so without leaching into the environment or losing effectiveness through touch.

Laboratory Success

In laboratory tests, surfaces coated with this paint demonstrated remarkable efficacy. For instance, the paint completely eliminated E. coli and Candida, while also reducing MRSA concentrations by an impressive 99.9%. Moreover, the paint maintained its antimicrobial properties even against bacteria evolved to resist chlorhexidine. This highlights not only its robustness but also its potential for long-term use.

Wide-Ranging Applications

Developed in collaboration with coatings manufacturer Indestructible Paint, this antimicrobial paint offers a practical and cost-effective solution for infection control. Furthermore, its applications extend beyond healthcare settings to include industries such as public transport and aerospace, where hygiene is especially important. The paint’s durability ensures sustained protection, making it a promising tool in the ongoing fight against surface-transmitted infections and antibiotic resistance.

This research underscores the potential of this innovative material to significantly enhance public health standards, while also reducing the transmission of harmful pathogens in a variety of environments.
