Figure 4. Elastic modulus of 10% alginate dialdehyde-gelatin hydrogels (70-30 wt%) with three angular designs: (1) each layer adhered to the underlying layer at 90° (0/90°); (2) the second layer adhered to the underlying layer at 45° and the third layer adhered to the first layer at 135° (0/45/135°); and (3) second layer adhered to the first layer (15°) at 165° (15/165°) (#,*P < 0.05).
