摘要：
Disclosed herein is an article that includes a first plurality of spaced features. The spaced features are arranged in a plurality of groupings； the groupings of features include repeat units； the spaced features within a grouping are spaced apart at an average distance of about 1 nanometer to about 500 micrometers； each feature having a surface that is substantially parallel to a surface on a neighboring feature； each feature being separated from its neighboring feature； the groupings of features being arranged with respect to one another so as to define a tortuous pathway. The plurality of spaced features provide the article with an engineered roughness index of about 5 to about 20.
