Development of biocide coated polymers and their antimicrobial efficacy

Microbial contamination of plastic surfaces is a significant source hospital-acquired infections. To produce antimicrobial surfaces, chlorhexidine was attached to nitrided acrylonitrile butadiene styrene (ABS). The uniformity distribution on the revealed by time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging. Its efficacy established against model pathogenic Gram-positive and Gram-negative bacteria, fungi, viruses. stability bonded evaluated via leaching test. rapidly killed microbes: no viable colonies Escherichia coli, Staphylococcus aureus, or Candida albicans were recoverable after 45 minutes. It effective SARS-COV-2, with virions found 30 Additionally, as in killing chlorhexidine-resistant strains bacteria they naïve strains. surface stable; 2 weeks leaching, detectable leachate. We believe that technology widely applicable prevent spread fomite infection.
