Printable ADA-GEL-based composite inks containing Zn-doped bioactive inorganic fillers for skeletal muscle biofabrication.

Bioprinting shows significant promise in advancing medical treatments by offering patient-specific solutions for repairing skeletal muscle tissues. Zinc (Zn) is one of the key ions in the human body involved in the development of myogenic cells. This study investigates the integration of Zn-doped bioactive inorganic fillers (BIFs) into alginate-dialdehyde-gelatin (ADA-GEL) as composite ink for bioprinting applications.
