Roger Narayan is young researcher working in the field of tissue engineering in the Department of Biomedical Engineering jointly operated by the University of North Carolina and North Carolina State University. Narayan, whose work was the subject of a story in the Bulletin, is both an M.D. and Ph.D. who has been working with several laser-based processes to combine advanced materials with tissue engineering. In this video, he discusses the three main processes he uses: pulse-laser deposition, laser-direct writing and two-photon polymerization. He describes some of the applications, such as building unique and customized tissue scaffolds, patient-specific devices and microneedles. He also discusses some of the current challenges facing researchers and the prospects for having some of these advances getting approval for widespread use in the medical community. |
