(a) Dynamic storage modulus (G′) and dynamic loss modulus (G″) as a function of time for a 1.0 wt% agarose solution in a 1× PBS buffer (pH 7.4) upon cooling the sample from 25 to 2 °C and maintaining at 2 °C. A strain amplitude of 1.0 % and a frequency of 1 Hz were used. The cooling rate was 3 °C /min. (b) Dynamic strain amplitude sweeps at frequencies of 0.5, 1.0, 2.5, and 5.0 Hz for a 1 wt% agarose hydrogel. The experiments were conducted at 2 °C after the agarose gel was formed on the bottom plate of the rheometer.
