Nanoimprinting of biomedical polymers reduces candidal physical adhesion

Abstract

Management of fungal biofilms represents a significant challenge to healthcare. As a preventive approach, minimizing adhesion between indwelling medical devices and microorganisms would be an important step forward. This study investigated the anti-fouling capacity of engineered nanoscale topographies to the pathogenic yeast Candida albicans. Highly ordered arrays of nano-pit topographies were shown to significantly reduce the physical adherence capacity of C. albicans. This study shows a potential of nanoscale patterns to inhibit and prevent pathogenic biofilm formation on biomedical substrates.
