The present invention relates to a reversible fluorescence photoswitch based on the dye-crosslinked dendritic nanoclusters for high-contrast imaging of living biological systems. The dendritic nanocluster according to the present invention consists of two or more dendrimers crosslinked each other to have a globular shape overall, and thereby enhancing the fluorescence intensity and improving the detection sensitivity of the monomeric dendrimers. In addition, the dendritic nanocluster according to the present invention was found to internalize into a living zebrafish by both skin permeation and microinjection, independently. Further, the dendritic nanocluster according to the present invention showed low toxicity and thus it could be useful for both in vivo and in vitro imaging as well as the ex vivo cell tracking applications.
