Advanced applications of chitosan-based hydrogels: From biosensors to intelligent food packaging system

As the only natural cationic polysaccharide, chitosan (CH) have several bioactivities. Moreover, CH was the ideal biomaterial for the preparation of hydrogels that have desirable biocompatibility and biodegradability. CH-based hydrogels have been extensively reported for their applications in delivery system and tissue engineering. Furthermore, CH-based hydrogels have shown great potential and attracted considerable attention in recent years for...
