Based on color wheel analysis [ 34 ], quantitative assessment showed that the AMS@Sema3A fiber had highly uniform orientations, all of which were centrally distributed within ±10°, while the MS and MS@Sema3A fibers showed a trend of orientation concentration ( Fig. 1 D), with statistically significant (p < 0.05) differences in the degree of orientation between the random and oriented groups ( Fig. 1 E).
