“…Due to these properties, CDs have applications in biomedical fields, such as drug delivery [4], fluorescent probes for clinical diagnosis [5], bioimaging [6], therapy [7,8], and artificial mimicking enzymes [9]. Recently, more and more intrinsic bioactivities of CDs have been explored and reported, such as homeostatic bioactivity [10,11,12], wound-healing activity [13], hypoglycemic bioactivity [14], hepatoprotective bioactivity [15], radical-scavenging activity [16], peroxidase-like activity [17], anticancer activity [7,18], and antibacterial activity [19,20]. However, as one of the most important nanomaterials, volumes of the studies concerned with CDs’ bioactivities are still small, and the functions of CDs have yet to be fully developed.…”
