Dynamic frequency-sweep oscillatory rheology measuring the storage moduli of 1 wt % hydrogels as a function of frequency. A 4-fold increase in storage modulus is achieved in the racemic hydrogel (■) with respect to either pure MAX1 (◇) or DMAX1 (●) gels (N = 3) (A). Time-sweeps of two racemic gels. The first prepared by allowing independent solutions of MAX1 and DMAX1 to self-assembly independently at 25 °C for 10 min, then mixed and further gelled at 37 °C (×). The second gel prepared by premixing solutions of monomeric unfolded MAX1 and DMAX1 and then triggering gelation at 37 °C (▲) (N = 3) (B).
