    2. Hydroxyapatite surfaces are created on a titanium substrate via a polymer templating sol-gel route. This is a low temperature method of producing porous HAp surfaces and avoids the problems associated with the phase transition of titanium at ~700ºC. The purpose of fabricating these surfaces is to determine the ideal surface roughness and porosity for cell attachment. The surfaces are characterized using various surface analysis techniques including XPS, SEM and ToF SIMS. The group has expertise in manufacturing surfaces of specific roughnesses including surfaces which exhibit superhydrophobicity. The School of Chemistry at UNSW has the largest surface analysis facility in the country; the group also regularly travels to Synchrotrons across the world to perform experiments which are not possible using conventional laboratory techniques.
