Hydrogels and hydrogel layers for the design of biocompatible surfaces
Surfaces and gels that are suited for applications in the biomaterials field have been a subject of intense research. Largely, this is due to the fact that good biomaterials provide tremendous business opportunities but also pose fascinating scientific challenges. The presentation will highlight some of our own approaches towards hybrid materials, mostly calcium phosphate composites, using soft matter strategies. These include polymer surfaces that have been tailormade to contain certain chemical groups supporting mineral formation, but also hydrogels or hydrogel thin films that are excellent growth media for both an inorganic mineral phase and bone cells. Moreover, the presentation will also introduce initial experiments involving 3D printed scaffolds and their surface modification along with first data on how ionic liquids can be used for the fabrication of biocompatible soft and hard materials, especially materials from starting materials that are less easy to process otherwise such as silk.
