Abstract: Carbon quantum dots (CQDs), as a new class of nanomeaterials, have exhibited broad appeal for chemical inspections according to their peculiar fluorescent properties. When interacting with detected molecules, their tunable fluorescence intensity can be applied in visual detection which includes FQ-type (fluorescent quenching) and FR-type (fluorescent recovery) detection. Compared with aqueous fluorescent sensors, paper-based devices are more extensively utilized in the field of substance inspections concerning their superiorities in portability, fast-response, on-site examination and visualization. Herein, we review recent research status and progress in the field of CQDs to provide a future perspective incorporating fluorescent properties of CQDs, current visual fluorescent inspections and paper-based sensors.
