Biomolecules are highly attractive materials which are produced and optimized by nature. They can meet complex challenges such as storage and release of water, biological signalling and even the formation of a biofunctional matrix to host living cells. We can modify biomolecules and use them in material design for bioprinting. We use the biopolymers from the native extracellular matrix in order to provide printable formulations of tissue specific matrices for printing and encapsulation of cells.
Examples for photo-crosslinkable biomolecules: methacryl-modified gelatin derivatives, methacryl- and acetyl-modified gelatin derivatives for non-gelling, low viscous solutions, methacrylated hyaluronic acid or chondroitin sulfate, methacryl-modified or benzophenone-modified heparin.
