Nanotechnology for Biomaterials

A long and rather densely written article from AzoNano.com examines the use and future of nanoscale engineering to develop ever more capable biomaterials for regenerative medicine: "Third-generation biomaterials that involve tailoring of resorbable polymers at the molecular level to elicit specific cellular responses show great promise as scaffolds or matrices in tissue regeneration. ... bioactive glasses and macroporous foams can be designed to activate genes that stimulate regeneration of living tissues. ... a future goal for regenerative medicine is the possibility of using bioactive stimuli to activate genes as a preventative treatment; maintaining the health of tissues as they age. Only a few years ago this concept would have seemed unimaginable. But we need to remember that only 30 years ago the concept of a material that would not be rejected by living tissues also seemed unimaginable!"
