One day doctors will grow new bones with nanotechnology

Abstract:
Nanotechnology-enabled tissue engineering is receiving increasing attention. The ultimate goal of tissue engineering as a medical treatment concept is to replace or restore the anatomic structure and function of damaged, injured, or missing tissue. At the core of tissue engineering is the construction of three-dimensional scaffolds out of biomaterials to provide mechanical support and guide cell growth into new tissues or organs. Biomaterials can be variously permanent or biodegradable, naturally occurring or synthetic, but inevitably need to be biocompatible. Using nanotechnology, biomaterial scaffolds can be manipulated at atomic, molecular, and macromolecular levels. Creating tissue engineering scaffolds in nanoscale also may bring unpredictable new properties to the material, such as mechanical (stronger), physical (lighter and more porous) or chemical reactivity (more active or less corrosive), which are unavailable at micro- or macroscales. For bone tissue engineering, a special subset of osteoinductive, osteoconductive, integrative and mechanically compatible materials are required. Such materials need to provide cell anchorage sites, mechanical stability, structural guidance and an in vivo milieu. Moreover, they need to provide an interface able to respond to local physiological and biological changes and to remodel the extracellular matrix (ECM) in order to integrate with the surrounding native tissue. Scientists in Singapore have developed a new nanoscale biocomposite that brings researchers one step closer to mimicking the architecture of the ECM.
