  1. Opportunities for Military Veterans in Biomaterials ResearchEric Mazur, Harvard University, DMR 1005022 The REU Site Biomaterials Research Initiative Dedicated to Gateway Experiences at Harvard includes an effort to provide military veterans opportunities to perform summer research. In summer 2011, two veterans worked under the guidance of Professor Kevin Kit Parker. Sergio Ortuno, a Navy veteran, of San Jacinto College, designed a rotating collector for a rotary jet-spinning device used for producing nanofibers for cell scaffolds. The improved collector resulted in more highly aligned nanofibers (right). Alexander Cho, a former Marine, of Bunker Hill Community College, worked to incorporate arrays of muscular thin films (MTFs) into microfluidic devices for rapid testing of cardiotoxicity. Muscular thin films are bio-hybrid polymer films covered with cardiac muscle cells that spontaneously contract. Drugs of interest can be introduced in the device and MTF response is measured. A time sequence of a MTF cantilever contracting. Each film’s displacement can be correlated to contractility which allows for direct comparison of drug’s effects on micro-tissues. Aligned nanofibers produced with a rotary jet spinner with a rotating collector with vertical movement. 111 ms 0 ms 55 ms 167 ms Kevin Kit Parker (back) with Sergio Ortuno (center) and Alex Cho (left). Josue Goss (right), also a veteran, and a former REU student, is currently the staff engineer for the Disease Biophysics Group and is pursuing a Masters in Biotechnology at the Harvard Extension School. 500 um
