Carbon quantum dots (CQDs) are a recently developed class of fluorescent nanoparticles made from carbon. Co-doping with heteroatoms such as nitrogen and sulfur improved the properties generated high yield. In proposed study, we utilized simple, cost-effective, single-stage hydrothermal approach to produce extreme photoluminescence co-doped, sulfur, CQDs (N,S-CODs). Thiosemicarbazide was used source, while citric acid carbon source probes. The prepared N,S-CQDs were subjected extensive characterization. yielded strong fluorescence emission at λ em 430.0 nm after excitation ex 360.0 nm, relatively yield 41.3% utilizing quinine sulfate reference compound. These applied nanosensors for ultrasensitive spectrofluorimetric determination baloxavir marboxil (BXM) directly without pre-derivatization first time. BXM effectively quenches native N,S-CQDs. Considering optimal conditions, intensity reduction exhibited ‘turn-off’ response concentrations 10.0–100.0 ng ml −1 , detection limits 1.88 quantitation 5.69 respectively. method determined successfully in its tablet dosage form further expanded confirm content uniformity units agreement USP guidelines.
