Figure 5. The adhesion strength between a material surface and a cornea tissue glued by a gelatin hydrogel.

Figure 5.

(A) The hydrogel was applied between a material and a porcine cornea, and the force was measured as the two were separated. (B) A representative force-extension curve for PDA-coated (red) and noncoated surface (blue). (C) PDA coating enhanced the adhesion between the tissue and the material. * p < 0.05, **p<0.01, (n = 4).
