Novel Microneedle and Micro-Blade Fabrication Technique for Biomedical Applications

This invention presents a novel needle fabrication technique for creating a sharp, beveled metallic microneedle. Using a SU-8 mold structure, needle tip geometry with beveled dimensions can be controlled in 3D. The same fabrication method can be adopted to create a micro-blade with controlled blade angle.

Benefits
Existing microneedle fabrication techniques are not able to control the needle tip geometry in 3D. The manufacturing method disclosed in this invention can produce a controlled sharp needle tip, for example, a tubular hollow needle with an angled tip, or other 3D tip geometries for various purposes. The microneedle can be used as a component in biomedical diagnostic devices for drug delivery, blood extraction, or transport. The micro-blade can be used for micro surgical applications.

Stage of Development
A formal patentability opinion is being considered at this time. This technology is part of an active and ongoing research program and includes a working prototype. It is available for developmental research support/licensing under either exclusive or non-exclusive terms.
