From: Study of 3D-printed chitosan scaffold features after different post-printing gelation processes
De-hydration profile of 3D CH-based scaffolds gelled with KOH (1.5M), Na2CO3 (1.5M), NH3(g) (from 28% ammonia solution) as a function of time. Scaffolds were exposed to vacuum oven at 40 °C until complete loss of water.
