Role of crosslinkers in advancing chitosan-based biocomposite scaffolds for bone tissue engineering: A comprehensive review.

Bone tissue engineering (BTE) aims to repair and regenerate damaged bone tissue by combining cells, scaffolds, and signaling molecules. Various macromolecules, including natural polymers like chitosan (CS), collagen, hyaluronic acid, and alginate, as well as synthetic polymers such as polyethylene glycol and polylactic acid, are used in scaffold fabrication. Among these, CS holds significant potential in BTE due to its biocompatibility, biodegradability, and other features.
