Abstract:
1. An article having a surface topography for resisting bio adhesion of organisms, comprising: a base article having a surface; a plurality of spaced apart features projected into said base surface, wherein each feature has a substantially different geometry than neighboring features, wherein neighboring patterns share a common feature; the plurality of spaced features arranged in a plurality of groupings wherein each grouping is identical with other groupings; wherein each grouping has at least three features having a substantially different geometry from each other; and the spaced features within each of the groupings being spaced apart at an average distance of about 0.5 micrometers to about 200 micrometers; the adjacent groupings of features being spaced from each other to define an intermediate sinusoidal pathway, wherein neighboring sinusoidal paths converge toward and diverge from each other in a substantially mirror symmetry; further wherein a width of each sinusoidal path as measured between two adjacent groupings is substantially uniform.
