DESCRIPTION:Nanostructured design of hybrid biomaterials for tissue enginee
 ring\nScaffolds are materials that can act as temporary templates for tiss
 ue growth. There are many design criteria for scaffolds for tissue enginee
 ring. A scaffold must bond to the tissue\, degrading as the tissue regener
 ates. To be an effective template the scaffold must have an interconnected
  pore network that is open enough for tissue ingrowth. Bioactive glass and
  ceramic scaffolds have all the biological properties but are brittle. The
  obvious alternative is to make composites\, but the inorganic and organic
  phases tend to resorb at different rates\, leading to material instabilit
 y. Hybrids have the potential to have bespoke design of mechanical propert
 ies and congruent degradation through interpenetrating networks of inorgan
 ic and organic components. They are synthesised by the sol-gel process\, w
 hich is a bottom-up process\, where a polymer is incorporated as a silica 
 network forms. Covalent coupling between the components is critical to the
 ir success. The chemistry is complex however. Examples will be given of hy
 brids synthesised of functionalised natural polymers\, e.g. gelatin\, and 
 polymers that are synthesised in-house. The range of scaffolds will be sho
 wn.
