Hybrid 3D Printing of Interfacial Polyelectrolyte Complex Formed between Hyaluronic Acid and Poly-L-lysine Hydrogels
Hyaluronic acid (HA), a principal component of the extracellular matrix (ECM), exhibits excellent biocompatibility, high water-retention capacity, and inherent biodegradability. α-Poly-L-lysine (PLL), a cationic polypeptide with favorable biocompatibility, is widely employed for surface modification to promote cell adh...
