using carbon dots as an emerging nanoagentsin biomedical and healthcare applications

Carbon dots (cds) provide distinctive advantages of strong fluorescence, goodphotostability, high water solubility, and outstanding biocompatibility, and thus arewidely exploited as potential imaging agents for in vitro and in vivo bioimaging.imaging is absolutely necessary when discovering the structure and function of cells,detecting biomarkers in diagnosis, tracking the progress of ongoing disease, treatingvarious tumors, and monitoring therapeutic efficacy, making it an important approachin modern biomedicine. numerous investigations of cds have been intensivelystudied for utilization in bioimaging-supported medical sciences. however, there isstill no article highlighting the potential importance of cd-based bioimaging tosupport various biomedical applications. herein, we summarize the development ofcds as fluorescence (fl) nanoprobes with different fl colors for potentialbioimaging-based applications in living cells, tissue, and organisms, including thebioimaging of various cell types and targets, bioimaging-supported sensing of metalions and biomolecules, and fl imaging-guided tumor therapy
