(a) Viscosities of LMW-HA and LMW-AHA with lowest and second highest equivalents of NaIO₄, determined at increasing shear stress; (b) Viscosities of HMW-HA and HMW-AHA with lowest and highest equivalents of NaIO₄, determined at increasing shear stress; (c) Determination of the gelation point of gel with 3.5% (w/w) HMW-AHA-0.5 and 0.10% (w/w) adipic acid dihydrazide using time sweep measurements; (d) Determination of gelation kinetics (storage (continuous line) and loss (dashed lines) modulus) of identical gel compositions with 3.5% (w/w) HMW-AHA-0.5 and 0.20% (w/w) ADH mixed in different solvent (distilled water, PBS and DMEM).
