Bactericidal Efficacy and Surface Morphology of Nanopatterned TiN Films Deposited by High Power Impulse Magnetron Sputtering.

This research is an interdisciplinary collaboration that is developing a new generation of super-hard antimicrobial coatings, based on transition metal nitrides, for medical devices, common touch surfaces and other diverse applications. These surfaces will combine biophotonic functionality and nano-structured morphology to kill microorganisms through nanopillar-induced cell rupture, plasmonically enhanced photocatalysis and thermal stress.
