Abstract: The carbon dot (CD)-based fluorescent probe is a new type of fluorescent probe have been developed in recent years. Comparing with the traditional biological labels such as traditional organic dyes, fluorescent chromatin and usual fluorescent nanomaterial, the CDs have unique advantages (good water solubility, chemical inertia, low toxicity, easy function, anti-light bleaching, tunable and biocompatibility) have attracted considerable attentions. At present, more than ten kinds of inexpensive and convenient methods such as hydrothermal methods have been developed for large-scale preparation of fluorescent CDs. It has been widely used in cell function research, detection of cell surface and functional molecules, imaging of tissues, and positioning of pathogens. The synthesis method in recent years, the luminescence properties depending on the size and wavelength, and the application of fluorescent CDs in bioimaging are briefly reviewed, and their application in the pathology of medicinal plants is forecasted. It is expected to provide some reference for expending the application range of fluorescent CDs in the field of bioimaging.
