(a) Ratio of the final-to-initial volume, V/V₀ of the confined microgel, plotted as a function of the degree of microgel confinement, D₀/d_c. V is the volume of the microgel completely localized in the constriction and maintained there for 5 min. The Young’s moduli of the microgels are 2.57 (), 8.26 (), 12.54 kPa (), and 20.21 () (corresponding to agarose concentration in the microgel of 2, 3, 4 and 5 wt%, respectively). The black line gives the theoretical result, equation (8), for V/V₀. (b) Variation in volume ratio for microgels confined to the constrictions with different entrance angles.
