Antimicrobial peptides (AMPs) are ubiquitous and display broad-spectrum antimicrobial activity that can control bacterial colonization of surfaces. Ceragenins are small-molecule mimics of AMPs and have several advantages over AMPs, including cost of manufacture and stability. A ceragenin, CSA-120, modified with an acrylamide group was directly incorporated into fluoropolymer coatings as a means of inhibiting bacterial biofilm formation. The ceragenin-containing coatings displayed improved performance. By conjugating a copper chelating group to the ceragenin, chelation of 64Cu by the conjugate was effective and provided a stable complex that allowed in vivo imaging. This conjugate may provide a means of identifying infection sites …
