(A) Size, (B) mass swelling ratio, and (C) calculated mesh size (ξ) of alginate beads measured as a function of immersion time in DI water for up to 10 days. The initial sizes of the 1-100 and 2-100 beads were significantly larger than those of the 1-200 and 2-200 beads (p < 0.05). (D) Initial mesh size of synthesized alginate beads. * denotes statistical significance (p < 0.05) compared with the 2-200 bead group and all other groups. ** denotes statistical significance (p < 0.05) compared with the 2-100 bead group and 1 wt. % groups. The initial mass swelling ratio followed a similar trend as the initial mesh size. By day 2 differences in mesh size and swelling ratio between all groups were significant (p < 0.05).
