“…Being a metal free-fluorophore, carbon dots are considered to be one of the economically viable materials with high water solubility and photo-stability. The highly biocompatible nature of carbon dots has made them a useful material in biomedicines as a way of providing effective alternatives for drug delivery in chemotherapy [ 21 , 22 , 23 ]. The advanced optical and luminescence properties of carbon dots (C-dots) have demonstrated impressive potency in photocatalysis, chemosensing, light emitting diodes (LEDs) and electrochemical sensing [ 24 , 25 , 26 ].…”

“…In addition, Chaudhary et al has transformed waste plastic polybags, bottles and cups into luminescent Cdots (5-30 nm diameter) by pyrolysis at 400°C under N 2 . [98] The C-dots exhibited good emission properties and relatively high quantum yield, which has been applied as selective Cu 2 + sensor in water by the fluorescence quenching. The high selectivity toward Cu 2 + sensing was ascribed to the intensive interaction between Cu 2 + ion and the surface functional groups of C-dots.…”

“…The synthesis of carbon dots (C-dots) is also reported in the literature [ 84 , 85 , 86 ]. The C-dots generated from plastic wastes possess superior biocompatibility, adjustable luminescence, and optical properties.…”

“…The C-dots generated from plastic wastes possess superior biocompatibility, adjustable luminescence, and optical properties. Chaudhary et al [ 84 ] utilized plastic wastes consisting of used cups, bottles, and polyethylene bags and the hydrothermal carbonization process to make fluorescent C-dots. The produced C-dots consist of different types of functional groups such as −COOH and −OH on the exterior surface, and they possess better water solubility.…”
