Characterization of assembled hydrogels. Percentages of resulting assemblies were plotted for (A) two-gel, (B) three-gel, (C) four-gel, and (D) five-gel combinations. These experiments were performed for two hydrogel sizes: 500 µm × 500 µm × 150 µm and 1000 µm × 1000 µm × 150 µm. Brackets connecting groups indicate statistically significant difference (n = 4, p < 0.05). “*” indicates statistically significant difference between all other groups. Error bars represent standard error of the mean. (E) Assembled hydrogels in different shapes. (F) Effect of magnet size on number of assembled hydrogels for different hydrogel sizes: 200 µm × 200 µm × 150 µm, 400 µm × 400 µm × 150 µm, 500 × 500 × 150 µm, and 1000 µm × 1000 µm × 150 µm. Brackets connecting groups indicate statistically significant difference (n = 8, p < 0.05). Error bars represent standard error of the mean.
