Abstract:
1. A method for manufacturing a microneedle array comprising providing a substantially planar substrate material; forming a plurality of first apertures in the substrate material, wherein the interior surface of at least one of the first apertures defines a microneedle having a tip, a base, and a body portion therebetween; forming a plurality of second apertures in the substrate material, each of the second apertures defining an elongated channel located in the body portion of the microneedle; and bending the microneedle near its base such that the tip and body portion project out of the plane of the substrate material, wherein the tip of the microneedle is tapered, the body portion is rectangular, and the channel extends through 50% to 99% of the length of the microneedle substantially from the planar substrate, through the base, and through at least a part of the body portion.
