The success of bone interfacing implants is strongly correlated to their osseointegration, their bonding with bone. However, little is known about the nanoscale structural and chemical attachment at bone-implant interfaces. We are using a variety of electron tomography and atom probe tomography approaches to study the bone-implant interface.
We are developing suitable biomaterials and surfaces for bone applications in dentistry and orthopaedics. We are exploring production and surface modifications including 3D-printing, electrospinning, laser-modification, and the associated in vitro and in vivo characterization for new biomaterials.
Utilizing state-of-the art approaches, including transmission electron microscopy, focused ion beam microscopy, atom probe tomography, and synchrotron-based studies we are probing the hierarchical structure and chemistry behind some of nature’s finest work, mineralized tissues.
