Biofunctional and cell-containing inks
If the inks contain biological materials such as biomolecules, cells, tissue preparations or biocompatible materials, the printed structures can perform a biological function. The biomaterial in its non-crosslinked, printable form is referred to as a bioink. The composition of these inks depends on the subsequent application. Thus, bioinks can be formulated with and without cells.
Bioinks for tissue engineering applications are optimized for the printing process and at the same time for the promotion of tissue-specific functions through targeted variation of the composition. We have already successfully produced "bone inks" and "vascularization inks" based on the available material construction kit. Both bioinks are dispersions of biomolecules and tissue-specific cells that can be stably formed into a 3D structure via dispensing processes.
Protein-containing bioinks should be processable while maintaining the native functionality of the proteins. We achieve this by using water-soluble and protein-compatible components. These inks can be used, for example, to make specific areas on a substrate attractive for adhesion of different cell types.
