(a) Real volume fraction ϕ versus experimental control parameter ζ as a function of particle elasticity, for (top to bottom) k = 1 × 104, 1 × 103, 5 × 102, 2 × 102, 1 × 102, and 5 × 101 Pa, with a0 = 50 nm and ϕp,0 = 0.1. (b) Extent of osmotic deswelling a/a0 with increasing particle volume fraction for the same settings as in (a).
