Cyclodextrin modified biocompatible Chitosan-Cinnamaldehyde Schiff base hydrogels: Their antibacterial, antioxidant, and drug delivery potential.

Chitosan (CS)-based hydrogels are promising platforms for drug delivery owing to their biocompatibility, biodegradability, and functional versatility. However, pure CS Schiff base hydrogels lack mechanical strength and rely on toxic cross-linkers, necessitating bio-safe alternatives viz. Cinnamaldehyde (CA).
