guanosine (G4)-hemin (GO/PVA/G4/H) hydrogel using a simple mixing method. Adapted with permission from. (C) Formation of a responsive
supramolecular DNA hydrogel based on Y-shaped branched DNA. Native PAGE was used to characterize the hydrogel matrix and linker synthesis, in
a molar ratio of 1:3. Lanes 1–4 correlate to the 32 nucleotide (nt) control sequence, s-L, B-Y, and B-Y + s-L, respectively. Images of the DNA hydrogel
stained with SYBR-gold and SYBR-green, respectively, were used to stain the B-Y and s-L samples. Adapted with permission from. (D) Self-assembly

functionalized G-quadruplex thermoresponsive hydrogel. Adapted from. (F) Formation of injectable metallo-nucleoside nanofibrous hydrogel.
