摘要

Biofilms cause life-threatening infections and contaminations, and traditional antimicrobial coatings suffer from biofouling as the formation of conditioning layer by cell debris. We developed a metal-coordinating polymer of poly(methacrylic acid) with Ag+, achieving both antimicrobial and antifouling properties. It reduced the viability of Pseudomonas aeruginosa, 70% of biofilm formation, and apparent toxicity that is demonstrated by 97% viability of human dermal fibroblasts (HDFa) treated by the supernatants from bacteria grown on the coating, compared to 8% on uncoated surfaces. Synthesized via initiated chemical vapor deposition (iCVD), this coating offers a scalable, substrate-independent solution for applications in healthcare and food manufacturing.
