Mechanical property of CS hydrogels.
(a) Modulus of hydrogel in different distance range, c(CS) = 4.0 wt.%; (b) Modulus of hydrogel samples prepared by different molds, which possessed different directions of orientation, c(CS) = 3.0 wt.%; Schematic showing the orientation in hydrogel samples and relative positions of orientation to the direction of compression. Error bars indicate standard errors for n = 3.
