CB-SAHs absorption (MUR) and elasticity (G′) in different aqueous media. (a) Hydration kinetics of a single CB-SAH particle (GelA in SGF/water 1/8 v/v), observable as a progressive increase in size with respect to a pencil tip, and visual appearance of the fully hydrated CB-SAH (0.25 g of GelA particles, with a size range 100–1000 µm, in SGF/water 1/8 v/v; scale bar 1 cm). (b) Set-up of the DMA analysis to measure the elastic modulus G′ and the viscous modulus G″ of the hydrated CB-SAH. (c) Exemplary DMA curves obtained for the CB-SAHs (GelA), indicating G′, G″ and the ratio G″/G′ (tan_delta), as a function of frequency. (d) G′ and G″ (at 10 rad/s) and MUR of the CB-SAHs upon incubation in SGF/water 1/8 v/v. (e) G′, G″ (at 10 rad/s) and MUR of the CB-SAHs upon incubation in PBS. In (d) and (e), results are the mean ± SD of three independent measurements. Plots in (c), (d) and (e) were produced with Origin 6.0, www.originlab.com. The different G′ of GelA and GelB02 is highlighted by **(p < 0.01).
