Abstract

A coated surface for resisting or enhancing bioadhesion includes at least one patterned polymer including coating layer having a plurality of features attached to or projected into a base surface. The features each have at least one microscale (<1 mm) dimension and have at least one neighboring feature having a substantially different geometry. The patterned coating layer preferably provides an average roughness factor (R) of from 4 to 50. The coating layer resists or enhances bioadhesion as compared to the base surface.
