Macroscopic observation of the hydrogels on the plate during rheological analysis. (a–c) Mixture of HA-Plasmid1 and HA-Plasmid2. (a) Sample just after mixing was liquid. (b) Hydrogel was obtained after the first analysis. (c) Stiff hydrogel was obtained after the second analysis. (d) Native HA aqueous solution. (e) Hydrogel obtained after the third rheological analysis was treated with restriction enzyme. The sample changed into liquid.
