Tissue Engineering Scaffold
report_problem Problem Statement
Tissue engineering scaffolds require biocompatible crosslinkers to stabilize natural polymer matrices (collagen, gelatin, hyaluronic acid) into mechanically robust, porous structures that support cell attachment and proliferation. Current crosslinkers—glutaraldehyde, EDC/NHS, and genipin—present trade-offs between cytotoxicity, cost, and mechanical performance. A bio-based crosslinker using food-grade compounds could provide safe, affordable scaffold stabilization with degradation rates matched to tissue regeneration timelines.
