Out-of-Plane, High strength, Polymer Microneedles for Transdermal Drug Delivery KU Leuven
XThis paper reports on the high strength of highaspect ratio (> 50) hollow, polymer microneedles fabricated out-of-plane using a fairly repeatable fabrication process. Further, these microneedle tips were sharpened by a molding principle, with a simple anisotropic etch of silicon wafer. Also, an enhanced elegant process was explored to incorporate the mounting of the microneedle onto a platform without using any additional material, such that ...
