1. An article comprising a microstructured surface capable of forming an adhesion to a contact surface wherein the microstructured surface comprises a plurality of microtextured islands each comprising a hierarchical pattern including at least a plurality of first microfeatures and at least a plurality of second microfeatures, the plurality of second microfeatures disposed about the plurality of first microfeatures, wherein the hierarchical pattern is configured to develop a hydrophobic/hydrophilic mixture when in contact with a liquid interface, such that the hydrophobic portion of the mixture associates with at least one of the plurality of first microfeatures or the plurality of second microfeatures, and the hydrophilic portion of the mixture associates with the microfeatures that do not develop the hydrophobic portion, and wherein adhesion occurs when the shear stress exceeds a normal force and the microstructured surface comprises a hysteresis angle of greater than 5 degrees.
