Abstract
A method of making a three-dimensional porous device entails providing a substrate having a conductive pattern on a surface thereof, and depositing a colloidal solution comprising a plurality of microparticles onto the surface, where the microparticles assemble into a lattice structure. Interstices of the lattice structure are infiltrated with a conductive material, which propagates through the interstices in a direction away from the substrate to reach a predetermined thickness. The conductive material spans an area of the surface overlaid by the conductive pattern. The microparticles are removed to form voids in the conductive material, thereby forming a conductive porous structure having the predetermined thickness and a lateral size and shape defined by the conductive pattern.
