Abstract
In recent years carbon dots (CDs) have emerged as a new class of carbon nano-structures with sizes <10 nm, due to their physico-chemical, biocompatible and strong tunable photoluminescence. We highlight here the importance, especially with the aim of cell labeling, by using CDs as probes. We then briefly present the state-of-the-art and the progress of bioimaging. We present many recent examples using CDs as cell labels for imaging of various cells.
