The swelling and deswelling behavior of multi-microchannel scaffolds with or without MWCNT. (a) showed that all the scaffolds reached a swelling equilibrium state at 180 min and the 0.025% MWCNT-agarose scaffolds had higher swelling ratio than others (∗P < 0.05). (b) showed the water retention of each scaffold decreased linearly with time. The 0.025% MWCNT-agarose scaffolds had higher water retention than the others after the 100 min (#P < 0.05).
