Facile and cost-effective preparation of carbon quantum dots for Fe3+ ion and ascorbic acid detection in living cells based on the “on-off-on” fluorescence principle
Abstract
Abstract A facile and cost-effective route of fabricating carbon quantum dots (CQDs) was proposed via simply hydrothermal treatment of lignin. Because of abundant aromatic structure and functional groups derived from lignin, the prepared CQDs (LCQDs) showed unique chemical and optical property. A remarkable fluorescence quenching effect of Fe3+ on LCQDs was found, resulting from the formation of non-fluorescence complex between LCQDs and Fe3+. This “on-off” fluorescence CQDs nanoprobe for Fe3+ allowed a wide linear range of 50–650 μM with the limit of detection (LOD) as low as 196 nM. Besides, ascorbic acid (AA) was found to reduce Fe3+ to Fe2+, leading to the recovery of the LCQDs fluorescence and a good linearity in range of 0–350 μM with a LOD of 5.34 μM. Furthermore, this sensing platform was successfully used for Fe3+ and AA monitoring in biological samples and intracellular imaging without surface modification.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
