Abstract

Methods for manufacturing a self-supporting substrate having a plurality of spaced-apart needles (spikes or microcapillaries) projecting upwardly from a major surface of the substrate. In a preferred method, metal is deposited onto a porous membrane such that the metal extends into the pores, after which the membrane is dissolved.
