Abstract

The incidence of inflammatory bowel diseases (IBD), including Crohn's diseases and ulcerative colitis, is increasing by time and showing a trend of younger age. Precise diagnosis and effective treatments for IBD have attracted growing attention in recent years. However, diagnosing and locating inflammatory lesions remain a great challenge for IBD. In this study, assisted by a kind of aggregation-induced emission (AIE) nanoprobes (BPN-BBTD nanoparticles [NPs]), the second near-infrared (NIR-II) fluorescence imaging is first utilized to accurately trace inflammatory lesions, monitor inflammation severity and detect the response to the drug intervention in IBD mouse models. Through the advantages of high signal-to-background ratio (SBR) and sharp spatial resolution of bio-imaging in NIR-II region, the NIR-II fluorescence imaging-guided surgery can help to achieve a complete resection of severe inflammatory bowls and a secure surgical anastomosis. In addition, with the help of NIR-II fluorescence wide-field microscopy, the distribution of BPN-BBTD NPs can be directly detected in tissue level and found to be mainly accumulated in mucosa and submucosa layers. This study highlights that AIE NPs-assisted NIR-II fluorescence imaging hold a great potential value for future diagnosis and imaging-guided surgery in IBD.

Statistics

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Each methylene unit inserted between donor and acceptor typically induces a red-shift of ~100 nm.

    “A general rule, as exemplified in cyanine dyes, is that each methylene unit inserted between donor and acceptor typically induces a red-shift of ~100 nm111–123.”

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.
