| Summary: | Abstract Surface contamination is an important, if under-discussed, route of infection transmission. In this study, we suspended chlorhexidine digluconate (CHX) in epoxy resin. CHX was found to be stably incorporated into the material, and its addition to epoxy resin was found to have minimal effects on the optical transparency of the material. After application of the epoxy resin to steel surfaces, time-of-flight secondary ion mass spectrometry revealed that CHX was uniformly present over the surface. Surfaces painted with CHX-resin were found to have significant, reproducible antimicrobial efficacy against E. coli, S. aureus, and C. albicans. We have shown that the addition of CHX has minimal effects on the adhesion of the epoxy resin to surfaces, as well as a high durability of the antimicrobial efficacy. We believe that this material has a wide array of applications, and could be utilised to confer significant, low-cost antimicrobial efficacy to existing surfaces, to prevent surface contamination, and to stop the transmission of infectious disease. |
