Rocket-shaped Microneedles

February 14, 2013
A scanning electron microscopy image of an array of rocket-shaped microneedles. The array was fabricated using two-photon polymerization. The small, cross-sectional area of this microneedle design serves to minimize the force necessary for skin penetration. A research team, led by researchers from North Carolina State University, developed two new approaches for incorporating antimicrobial properties into microneedles--vanishingly thin needles that hold great promise for use in portable medical devices. Researchers expect the findings to spur development of new medical applications using microneedles. This research award, titled "Two Photon Induced Polymerization of Microstructured Medical Devices," was supported by a grant from the National Science Foundation's Faculty Early Career Development (CAREER) Program (grant CMMI 05-47491). The objective of the project was to use two photon polymerization in order to create microstructured devices, including microneedles, for medical applications. Credit: Roger J.
