Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Structural rearrangement of LJ-GSH significantly enhanced intramolecular charge transfer, restoring strong fluorescence emission at 815 nm/910 nm.

    “The structural rearrangement significantly enhanced intramolecular charge transfer (ICT), thereby restoring strong fluorescence emission at 815 nm/910 nm.”
  • Within tumor cells and tissues, overexpressed GSH reacted specifically with LJ-GSH via an aromatic nucleophilic substitution reaction, leading to formation of a thiol skeleton.

    “Within tumor cells and tissues, overexpressed GSH reacted specifically with LJ-GSH via an aromatic nucleophilic substitution reaction, leading to the formation of a thiol skeleton.”
  • Yu et al. reported a glutathione-activatable NIR-II probe, LJ-GSH, which initially exhibited quenched fluorescence due to the weak electron-donating nature of its thiophenol group.

    “Yu et al. reported a glutathione (GSH)-activatable NIR-II probe, LJ-GSH, which initially exhibited quenched fluorescence due to the weak electron-donating nature of its thiophenol group106.”
  • The GSH-responsive activation mechanism of LJ-GSH substantially improved the probe's tumor-targeting specificity.

    “This GSH-responsive activation mechanism substantially improved the probe’s tumor-targeting specificity.”

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.
