Research output: Patent

Abstract

A system of topographic patterns for the prevention of bacterial adhesion and biofilm formation. The patterns may be provided on the surfaces of certain devices that are prone to bacterial adhesion and biofilm formation, such as urinary catheters. To reduce bacterial adhesion and biofilm formation, and to remove existing biofilms, the patterns are induced to transform from a first topography to a second topography. For example, the surface patterns may be formed from a shape memory polymer and then heated to transform the patterns from the first topography to the second topography to dislodge bacteria and prevent fouling.
