Surface topographies for non-toxic bioadhesion control

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.
