Fruit spoilage caused by oxidation and microbial infection exacerbates resource wastage. Although starch films including chitosan possessed admirable biocompatibility owing to great biodegradability compared with conventional plastics, deficient antibacterial antioxidant capacity restricted food shelf life. Herein, an environmentally friendly film (CS/G-CDs) was constructed carbon dots derived from Cirsii Herba (CDs), which formed through high affinity resulting hydrogen bonding between molecules hydroxyl originating CDs. The prepared CDs presented homogeneous monodisperse spherical structures ultrasmall size, providing favorable conditions for uniform formation. Encouragingly, the of CS/G-CDs increased 5.00-fold, followed rate up 97.0%. Dramatically, revealed glorious UV shielding efficacy (99.9% UVB 98.2% UVA), its preservation time blueberries remarkably extended 8 days longer than that film. Overall, Chinese herb-derived exhibited magnified antibacterial/antioxidant properties biocompatibility, provided a promising strategy sustainable development packaging materials.
