1. A device for promoting blood coagulation comprising:
a hierarchically arranged microstructured surface comprising at least a first surface texture and a second surface texture, the second surface texture being hierarchically disposed on the first surface texture, wherein the at least two surface textures are configured to create a plurality of spatially distributed surface energy gradients via Wenzel-Cassie wetting states, wherein a first portion of the microstructured surface generates Cassie wetting states, and a second portion of the microstructured surface generates Wenzel wetting states, the first portion of the microstructured surface having a higher contact angle than the second portion of the microstructured surface, wherein the hierarchical arranged microstructured surface is configured to have a fractal dimension of between 2 and 3, and wherein the microstructured surface is configured to promote thrombus formation when in contact with blood.
