(a) Microgel median and average diameters measured from optical microscope images. (b) Equilibrium swelling ratio of microgels in deionized water and PBS. The swelling ratio in deionized water increased with increasing concentration of SMA in the hydrogel formulation. The change in swelling ratio occurs to a lesser degree in PBS. *p < 0.05 as compared to HG-0 in PBS. #p < 0.005 as compared to HG-0 in water.
