Rheological and thermal characterization of bioinks. (a) The viscosity of two hybrid bioinks formulation (4A1CNF, 2A4CNC) and their separate components (4A, 1CNF, 2A, and 4CNC) as a function of shear rate. (b) Storage modulus (G’) and loss modulus (G’’) of two bioink formulations (4A1CNF and 2A4CNC). (c) Swelling (water absorbance) of dried patches made with these two bioinks over up to 96 h. Differential scanning calorimetry (DSC) analysis results (d) and thermogravimetric analysis (TGA) results (e) of freeze-dried 4A1CNF and 2A4CNC samples.
