Renal‐clearable Molecular Semiconductor for Second Near‐Infrared Fluorescence Imaging of Kidney Dysfunction
Open accessAbstract
Real‐time imaging of kidney function is important to assess the nephrotoxicity of drugs and monitor the progression of renal diseases; however, it remains challenging because of the lack of optical agents with high renal clearance and high signal‐to‐background ratio (SBR). Herein, a second near‐infrared (NIR‐II) fluorescent molecular semiconductor (CDIR2) is synthesized for real‐time imaging of kidney dysfunction in living mice. CDIR2 not only has a high renal clearance efficiency (≈90 % injection dosage at 24 h post‐injection), but also solely undergoes glomerular filtration into urine without being reabsorbed and secreted in renal tubules. Such a unidirectional renal clearance pathway of CDIR2 permits real‐time monitoring of kidney dysfunction in living mice upon nephrotoxic exposure. Thus, this study not only introduces a molecular renal probe but also provides useful molecular guidelines to increase the renal clearance efficiency of NIR‐II fluorescent agents.

“A caveat is that attaching highly hydrophilic side groups such as β-cyclodextrin (β-CD) 56 and poly(oligo(ethylene glycol) dimethacrylate) polymer brushes 48 to NIR-II fluorophores can facilitate renal excretion, but this typically lowers the fluorescence QY due to non-radiative relaxation of…”

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.
