Fig. 4. (A) Schematic pH-stimulated release of coralyne from the coralyne-loaded triplex-stabilized hydrogel upon subjecting the hydrogel to pH = 10.0. (B) Rheology studies comparing the effect of pH on the storage moduli, G′, and the loss moduli, G′′, of the (6)/(7) hydrogel, curves (a) and (b), respectively, to the effect of pH on the storage moduli, G′, and loss moduli, G′′, of the coralyne-loaded hydrogel, curves (c) and (d). (C) Time-dependent fluorescence changes upon subjecting the coralyne-loaded (6)/(7) hydrogel to variable pH values, resulting in the release of coralyne: (a) pH = 7.0 (b) pH = 8.0 (c) pH = 9.0 (d) pH = 10.0.
