Antimicrobial Paint Developed to Eliminate Pathogens on Contact

University of Nottingham researchers create durable, chlorhexidine-infused coating that kills bacteria and viruses without leaching, advancing infection control efforts.

Bug-Busting Antimicrobial Paint Can Make Surfaces Pathogen-Proof – From Staph to E. coli

Overview

  • The newly developed paint embeds chlorhexidine in epoxy resin, creating a germ-killing surface that remains effective without leaching into the environment.
  • Laboratory tests showed the paint completely eliminates E. coli and Candida, reduces MRSA by 99.9%, and works against chlorhexidine-resistant strains.
  • Durability trials confirmed the paint retains its antimicrobial properties after repeated exposures, leaching tests, and three months of storage.
  • The technology uses commercially available materials, making it a cost-effective solution for healthcare and other high-risk environments.
  • Further testing and optimization are ongoing to meet standards required for commercial approval and deployment.
