Abstract

In this work, the antimicrobial properties of vertically aligned nano-tubular Cu arrays (NT-Cu) fabricated via a template-based electrodeposition approach were investigated. The NT-Cu display good bactericidal activity against S.aureus and bacteriostatic properties against E.coli, S.sonnei, S.enterica and C.albicans. In contrast, Cu-foil electrodeposited from the same solution shows low biological activity against the same microorganisms. The antimicrobial activity of NT-Cu depends on both the type of microorganism and exposure time. After 6 hours of exposure, over 99.99% (log red = 4.43) of S.aureus population was inactivated, whereas, for E.coli, S.sonnei, S.enterica and C.albicans it was 97.8, 94.2, 89.9, and 90.3%, respectively.
