Rhomboidal Pt (II) metallacycle-based NIR-II theranostic nanoprobe for tumor diagnosis and image-guided therapy
Open accessAbstract
Significance The biomedical applications of fluorescent anticancer agents in the first near-IR region (NIR-I) have been hampered by problems of photostability, autofluorescence, and limited penetration depth in biological tissues. To shift the fluorescence theranostic region from the NIR-I to the longer-wavelength region for accurate cancer diagnosis and treatment, Pt(II) metallacycle-based fluorescent nanoprobe 1 with fluorescence emission in the NIR-II region is designed. In vitro and in vivo studies demonstrate that 1 has good photostability and the ability to efficiently inhibit the growth of tumor with minimal side effects. It also improves the fluorescent imaging quality and signal-to-noise ratio for cancer theranostics. This study provides an opportunity for further design of NIR-II theranostic anticancer agents for future biomedical applications.

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.
