A novel nitrogen-doped carbon dots as “on-off-on” fluorescent sensor for ultrasensitive and visual quantitative detection of mercuric (II) and glutathione

Carbon dot as fluorescence sensor for glutathione in human serum samples: a review

“…This study validates the efficacy of NCDs as a practical material for the naked-eye detection of GSH in real-world samples. 134 Chu et al introduced a portable sensing platform, comprising a ratiometric FL sensor integrated with a smartphone device, enabling sensitive, quantitative, and immediate determination of GSH levels in serum. The suppressed FL can rapidly recover upon interaction with GSH.…”
