Comparative studies of various compositions of bio-active glasses, ceramics and glass ceramics have established that there is a considerable range of levels of bioactivity, as measured by rates of bone bonding to bulk implants, or the rate of bone proliferation in the presence of bioactive particulates. A very limited range of bioactive glass compositions exhibit a high bioactivity index and bond to both bone and soft connective tissues; the biological response to bioactive gel-glasses made from the Ca0-Si02-P205 system provides evidence that tissue regeneration is possible, at least in bone. A fundamental understanding of the structural development and the relationship of structure to properties are called for: this proposal will apply an advanced chemical physics based materials characterisation methodology to examine a range of biomaterials of fundamental interest. The proposed research programme centres on the exploratory study of the structural properties of an important set of gel-produced bio-active materials on the atomic (1-10A) scale using an extensive characterisation methodology based upon state-of-the-art MAS NMR equipment and world-class neutron and X-ray facilities. The work will involve in-situ/time-resolved studies of key stages in the materials processing, and be explicitly focused on providing an improved understanding of their bio-active properties. This project will concentrate on Ca0-Si02 materials as there are existing medical uses and some fundamental structural questions related to the environment of calcium in silica, with extension to systems with small additions of phosphorus.
