主　　题：Carbon dots Bio-nanocomposite Gelatin UV shielding Intelligent packaging 

摘      要：Carbon dots(CDs)with intriguing fluorescent property,good biocompatibility,high stability,easy interaction with substrates,are burgeoning carbon nanoparticles with large potential in various *** CDs into the polymer matrix is becoming a popular strategy to endow the complex with new ***,the green-synthesized CDs was integrated into the mixture of gelatin(derived from waste fish scale)and chitosan,and a multifunctional bio-nanocomposite(defined as Gelatin/Chitosan/CDs)film was developed,which showed the excellent antibacterial,antioxidant,pH-sensitivity,UV shielding,and blue-emission *** effects of different concentrations of CDs on the physical,mechanical,structural,and functional activity of bio-nanocomposite film were *** with the Gelatin/Chitosan film,the Gelatin/Chitosan/CDs film with an optimum addition of 20%CDs showed the enhanced antibacterial,antioxidant as well as UV shielding *** importantly,it was used as an effective packaging material for fish meat preservation,reducing the loss of nutritional quality consumption,extending the shelf life of ***,the bio-nanocomposite films also possessed the anti-counterfeiting and pH-responsive properties due to the strong fluorescent emission of CDs,and had the great potential in developing the intelligent packaging *** work shed new light on the new application of CDs and the synthesis of bio-nanocomposite film in food industry.
