Antimicrobial coatings are vital in preventing bacterial contamination but a versatile solution does not exist. Structurally nanoengineered antimicrobial peptide polymers (SNAPPs) were recently developed to fight multidrug-resistant bacteria. To expand their application into antimicrobial coatings across a range of surfaces, a simple and universal coating strategy is needed. By developing phenolic-functionalised SNAPPs, this project aims to exploit the adhesive nature of metal–phenolic materials to rapidly coat diverse surfaces, including stainless steel and textiles. The expected outcome is the generation of antimicrobial polypeptide surfaces, which will have benefits in food safety, medical implant technology and advanced textiles.Read moreRead less
