Nanoengineering the surface of corneal implants: towards functional anti-microbial and biofilm materials

Abstract

We report the development and use of a light-mediated in situ grafting technology for the surface modification of biosynthetic corneal implants with peptide-capped nanoparticles (15–65 nm). The resulting materials have antimicrobial properties in bacterial suspension and also reduced the extent of biofilm formation. Our in situ grafting technology offers a rapid route for the introduction of antimicrobial properties to premoulded corneal implants, and potentially other soft implant targets.
