As with all glasses, phosphate based glasses offer a rich and diverse chemistry however the phosphate system offers the unique property of complete degradability. This coupled with the ability to alter the degradation rate over several orders of magnitude allow tailoring of the properties to suit a particular application.
Considering the potential biomedical applications the structure of these glasses is poorly defined, but with the application of a range of advanced probes such as NMR, EXAFS and XANES, the structure is now more clearly understood. In particular doping of glasses has given an indirect way to determine the structure of the glasses. These dopants have also given rise to an understanding of the effect of trace elements on cell behaviour.
More recently, developments in sol-gel synthesis have allowed compositions to be obtained, not normally attainable via traditional melt quenched routes and have also opened up the possibility of the use of phosphate based glasses for drug delivery applications.
