Description:
Col-Alg bioink is composed of collagen and sodium alginate, and the ratio can be customized. As the main component of extracellular matrix, collagen has the advantages of good biocompatibility, low immunogenicity and easy degradation. Sodium alginate is a natural biopolymer derived from algae. Col-Alg bioink has excellent biocompatibility and ionic crosslinking and are widely used to facilitate the formation of necessary cell-supporting tissue structures.
