Carbon quantum dots: Preparation, optical properties, and biomedical applications
Open accessAbstract
As an excellent fluorescent nanomaterial, carbon quantum dots (CQDs) have the properties of small molecular weight, small particle size, high fluorescence stability, no optical flicker, wide excitation spectrum, continuous, long adjustable emission wavelength, good biocompatibility and low toxicity. At present, it has been widely used in biological detection, in vivo and in vitro imaging, drug delivery and diagnostic drugs. This review presents a broad overview of recent progress in synthesis, optical properties, and biomedical applications of CQDs. The synthesis methods of CQDs are first introduced, followed by an extensive discussion of its purification, surface functionalization methods and stability. Furthermore, the optical properties of CQDs are presented, with an emphasis on photoluminescence mechanism and the relationship between synthesis conditions and optical properties. This review's much focus is given to the biomedical applications of CQDs, including detection, imaging (in vivo and in vitro imaging) and drug delivery (targeted therapy, photodynamic and photothermal therapy, and immunological and gene therapy). Finally, we cover the key issues and future prospects/advances that CQDs still have to deal with in the biomedical sector as well as possible solutions.

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.
