Once stable crosslinked hydrogels were produced, their susceptibility to protease was investigated. Initially, the degradation of the crosslinked hydrogels in the presence of the isolated serine protease trypsin was investigated using rheology. In solution with 0.5% trypsin, all the 7.5wt% G hydrogels showed a significant decrease in their storage modulus as they were degraded (Figure (a) and Table ). In contrast, the storage modulus of hydrogels in tris-buffer did not change significantly over the same timescale. (Figure (b) and Table ).
