Supramolecular hydrogels can be diluted to disrupt the gel network and release drug cargo. (a, b) For the stiffest gel formulation (2:10), 4× dilution with PBS buffer allows the material to flow. Bar chart data at 1 s^–1 shear rate. (c) Inverted vial test indicating an approximate gel-to-sol transition upon 4× dilution of the 2:10 gel formulation. (d, e) For the significantly less stiff 2:2 gel formulation, a 2× dilution with PBS buffer allows the material to flow. (f) Inverted vial test indicating an approximate gel-to-sol transition upon 2× dilution of the 2:2 gel formulation.
