a Schematic of the unconfined uniaxial compression test. b Young’s moduli from compression tests of soft A1.25 (1.25 wt% alginate; left), medium A2.5 (2.5 wt% alginate; middle), and rigid A5 (5.0 wt% alginate;, right) hydrogels. Poloxamer concentration indicated as 0.0 (black), 2.5 (blue), 5.0 (green), and 10.0 wt% (red) bars. Error bars represent range.c c Stress–strain curves for the rigid A5 hydrogels across all Poloxamer concentrations. d Cryo-electron micrographs of fracture surfaces of the rigid A5 gels with varying poloxamer concentrations. Scale bars = 10 µm.
