“…12 Carbon dots are luminescent zero-dimensional carbon nanomaterials that possess unique physical and chemical properties, good biocompatibility, low toxicity, and easy-to-functionalize surfaces. 13 These properties have made them attractive agents for biological imaging, 14 environmental monitoring, 15 chemical analysis, 16 targeted drug delivery, 17 disease diagnosis and therapy, 18 and anticounterfeiting applications. 19 A cost-effective means of upcycling plastic waste into carbon dots would create value-added products and reduce total waste.…”
