“…Carbon quantum dots (CQDs) are a relatively new class of nanomaterials with high biocompatibility and antimicrobial activity which can be prepared usually through a facile hydrothermal process. , Fabrication of active packaging films via the incorporation of CQDs has gained increased attention in recent years. Riahi et al prepared chitosan-based CQDs with a size of around 8 nm and incorporated them into the CMC/glycerol films for the fabrication of functional films with strong antioxidant and antimicrobial activity . These CQDs made the CMC films stronger and stiffer with reduced flexibility.…”

“…To date, the synthesis of carbonised polymer dots can be carried out using a variety of polymers [64]. To improve the fluorescence properties, regulating the surface state of carbon nanomaterials [65], increasing the crosslinking degree of polymers [66,67] and increasing the conjugation degree of carbonised polymer dots [68,69] have been widely accepted.…”

“…To improve the fluorescence properties, regulating the surface state of carbon nanomaterials [65], increasing the crosslinking degree of polymers [66,67] and increasing the conjugation degree of carbonised polymer dots [68,69] have been widely accepted. Most of the research on carbon dots has focused on the visible light region [62,64]. The near-infrared properties are also of great interest [70].…”

“…Therefore, the impregnation of Cdots in polyelectrolyte microcapsules produced via the subsequent deposition of oppositely charged polymers holds promise as an effective approach for the design of structures with competitive potential for applications in biotechnology for imaging, drug delivery, and biosensors [ 14 , 15 , 16 ]. Moreover, because of the versatility of the properties and dimensions, Cdots have promising potential for the design of functional coverages [ 17 ].…”
