SEM images of agarose lyophilized (LYO; (a–c)) and supercritically-dried (SCD; (d–f)) and AG33HA67 composite LYO (g–i) and SCD (k–m) at three different magnifications. The scale bar is 10 $\mathsf{\mu }$$\mathrm{m}$ (left), 1 $\mathsf{\mu }$$\mathrm{m}$ (middle), and $0.2$ $\mathsf{\mu }$$\mathrm{m}$ (right), respectively.
