| Abstract Scope |
One of the active areas of research in implant technology is to enhance biocompatibility through the development of novel biomaterials. The overall objective is to use hydroxyapatite (HAp) and graphene oxide (GO) to increase implant stability, imaging compatibility, and disrupt biofilm development. Our current research is focused on optimizing HAp and GO formulation ratio specifically creating samples using: 15 vol% HAp, 15 vol% HAp + 1% GO, and 15 vol% HAp + 5% GO. A systematic design of experiment was done to test different suspension formulations through slip casting and sintering, followed by extensive characterization that included Zeta potential measurements and Scanning Electron Microscopy (SEM). These tools allowed us to assess and refine suspension stability, microstructure, and homogeneity resulting in sintering densities reaching 70–90% of the theoretical maximum. In vitro studies with collaborators will explore cellular responses and functional properties, advancing both fundamental knowledge and translational potential. |
