Recent advances in biomedical materials technology hold the promise of a revolution in clinical medicine. These advances are being made possible by a convergence of technologies arising from a wide array of scientific discoveries. This convergence, however, is presenting new challenges as well as new opportunities. To explore these findings and to discuss possible ways to overcome the challenges, a workshop on this topic was held under the auspices of the NRC s Roundtable on Biomedical Engineering Materials and Applications. This report and accompanying CD provides a summary and the proceedings of the workshop. They present discussions of the context for new biomedical materials and of the three emerging technologies that were covered at the workshop: stem cells as biomaterials of the future, biomolecular materials composites, and superamolecular/nanoscale engineering and design.
