Figure 1. — (a) A schematic diagram showing the procedures for the fabrication of a CY gel. (b) Schematic representation of the 1,5-pentanedial-mediated covalent crosslinking reaction held between CS and LY. The pink molecule and green molecule represent a CS molecule and an LY molecule, respectively. (c) Photos depicting changes in the reaction mixture during the gelation process exhibited by different CY gels. The photos are taken at (a) 0 min, (b) 40 min, (c) 80 min, (d) 120 min, (e) 160 min, and (f) 200 min after the addition of 1,5-pentanedial.
