Surface topographies for non-toxic bioadhesion control

An article having a surface topography for resisting bioadhesions of organisms comprising:

• a base surface;
• a plurality of spaced features;
• wherein each feature has a surface that is substantially parallel to a surface of a neighboring feature, and wherein each feature has a substantially different geometry than neighboring features;
• the plurality of spaced features arranged in a plurality of groupings, wherein each grouping has at least three features having a substantially different geometry from each other;
• 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.
