Silver-coated Ceramic Microneedles

February 14, 2013
A scanning electron microscopy image of an array of silver-coated, organically-modified, ceramic (Ormocer®) microneedles, which was fabricated using two photon polymerization-micromolding and pulsed laser deposition. The antimicrobial activity of the silver-coated, organically-modified, ceramic microneedles against Staphylococcus aureus was demonstrated using an in vitro assay. 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.
