ABSTRACT

Cross-linkable gelatin methacryloyl (GM) is widely used for the generation of artificial extracellular matrix (ECM) in tissue engineering. However, the quantification of modified groups in GM is still an unsolved issue, although this is the key factor for tailoring the physicochemical material properties. In this contribution,
