Frederik Claeyssens is a Lecturer in Biomaterials at the Department of Materials Science and Engineering. He joined the department in 2008 from the Chemistry Department at the University of Bristol where he was a Research Fellow at the Life Sciences Interface. He obtained his first degree in Chemistry at Ghent University (Belgium) and his PhD in Chemistry at the University of Bristol and he was a PDRA at the University of Birmingham and the University of Bristol. His research group is based in the Kroto Research Institute (www.shef.ac.uk/northcampus).
Frederik´s research expertise focuses mainly on laser processing of biomaterials, and its applications. This research portfolio can be divided into three projects:
- Coatings for biology: Biocompatible coatings of semiconductors to be integrated into cell-silicon interfaces for biosensors. These coatings are currently investigated for in vivo/in vitro recording devices of electroactive cells (heart/brain cells).
- Bioprinting: Laser based techniques for printing biomolecules/cells for producing biomolecule arrays and biosensors. I have further developed this technique as a parallel direct-write technique, able to print 1000 pixels in one single laser shot. This technique is able to print viscous fluids containing DNA, proteins and even living cell.
- Biomaterials manufacture via microstereolithography: Using top down approaches to controllable (via CAD/CAM) produce 3D biocompatible/degradable polymer structures with micrometer resolution. Combination of this technique with bottom-up approaches to achieve hybrid biomaterials as 3D scaffolds for implants, tissue engineering and pharmaceutical testing.
Additionally, Frederik has also a keen research interest in computational solid state and biological chemistry. His previous work in this area includes predicting the stabilisation mechanism for the growth of polar wurtzite surfaces based on the existence of a low energy graphite-like structure (or h-BN) for ultra-thin wurtzite films. This model has recently been confirmed experimentally and forms the basis for understanding growth of polar surfaces in a large number of key technological materials (e.g. ZnO, GaN, CdSe and SiC). Additionally, Frederik has studied enzyme reactions on an unprecedented high level of theory, providing powerful new tools for modelling enzyme reactions, and enabling for the first time the study of enzyme reactions computationally with chemical accuracy.
