Au‐Doped Ag2Te Quantum Dots with Bright NIR‐IIb Fluorescence for In Situ Monitoring of Angiogenesis and Arteriogenesis in a Hindlimb Ischemic Model
Abstract
Fluorescence located in 1500–1700 nm (denoted as the near‐infrared IIb window, NIR‐IIb) has drawn great interest for bioimaging, owing to its ultrahigh tissue penetration depth and spatiotemporal resolution. Therefore, NIR‐IIb fluorescent probes with high photoluminescence quantum yield (PLQY) and stability along with high biocompatibility are urgently pursued. Herein, a novel NIR‐IIb fluorescent probe of Au‐doped Ag 2 Te (Au:Ag 2 Te) quantum dots (QDs) is developed via a facile cation exchange method. The Au dopant concentration in the Ag 2 Te QDs is tunable from 0% to 10% by controlling the ratio of supplied Au precursor to Ag 2 Te QDs, resulting in a wide range of PL emission in the NIR‐IIb window and a much‐enhanced PL intensity. After surface modification, the Au:Ag 2 Te QDs possess bright NIR‐IIb emission, high colloidal stability and photostability, and decent biocompatibility. Further, in vivo monitoring of the process of angiogenesis and arteriogenesis in an ischemic hindlimb is successfully performed.

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.
