Abstract
A device comprising a microstructured surface wherein in one aspect, the microstructured surface is arranged hierarchically with dual-functioning textured features. The surface may achieve adhesive properties by varying the parameters of the microstructure features. Additionally, the surface may achieve cellular and/or tissues in-growth functionality by varying the same parameters. Generally, the dual-functional aspect includes at least one surface feature having a varied periodicity which may be imposed on at least one other surface feature.
Claims8
A microstructured surface comprising:
- a substrate having a microstructure pattern comprising a plurality of first set of microstructure features and a plurality of second set of microstructure features, the plurality of first set of microstructure features being disposed about the substrate and having a spacing between adjacent microstructure features from 100-1000 microns, the plurality of second set of microstructure features being smaller than the first set of microstructure features and disposed hierarchically on the plurality of first set of microstructure features, and wherein at least one of the plurality of first set of microstructure features or the plurality of second set of microstructure features includes a width that varies periodically across the substrate;
- wherein the plurality of first set of microstructure features comprise a cross sectional profile varies periodically from circular to oval across the substrate, such that the variation repeats across the x-axis and y-axis of the substrate creating a modulated pattern, and wherein the microstructure pattern is configured to generate a Wenzel Cassie wetting state when interacting with a target surface and a fluid.
