N,S-Co-Doped Carbon Dot-Reinforced Biopolymer Films with Enhanced Barrier, Antioxidant, and Antimicrobial Performance for Active Food Packaging
The development of sustainable active food packaging materials with multifunctional protective capabilities is highly desirable for improving food safety and extending shelf life. In this study, sulfur- and nitrogen-rich carbon dots (GLCDs) were synthesized from glycine and lipoic acid through a facile hydrothermal app...
