Abstract:
1. A method of fabricating a microneedle, said method comprising: (a) forming a recess with an apex in a substrate; (b) forming a seed layer on the substrate including the recess; (c) forming a nonconductive pattern on a portion of the seed layer that is on a sidewall of the recess; (d) plating an electrically conductive material on the seed layer and over the edge of the nonconductive pattern to create a plated layer with an opening that exposes a portion of the nonconductive pattern and is laterally offset from the apex; and (e) separating the plated layer from the seed layer and the nonconductive pattern to release a hollow microneedle comprising a tip and an opening laterally offset from the tip.
