“…Compared with traditional organic dyes, QDs have high photostability, larger Stokes shift, higher brightness, high fluorescence quantum yield, and longer fluorescence lifetime . Furthermore, QDs can be further enhanced in terms of stability and biocompatibility through surface ligand modification , and can be loaded with specific targeting motifs and therapeutic agents, providing more possibilities for their applications in medical imaging and therapy. − So far, the commonly used luminescent QDs are mostly II–VI semiconducting nanomaterials, such as Cd(S, Se, and Te) QDs, − types of which have been the subject of significant controversy in biological applications due to their heavy metal content. Thus, some biocompatibility and nontoxicity QDs have been increasingly applied in diagnosis and treatment in recent years, such as Zn(S, Se, Te) semiconductor QDs. − Therefore, developing a new type of quantum dot nanomaterials with low toxicity and utilizing precise fluorescence-guided imaging would be highly beneficial.…”
