摘要：

The stable bioimaging with nanomaterials in living cells has been of great challenge and importance for understanding intracellular events and elucidating various biological phenomena. Herein we demonstrate the N, S co-doped carbon dots (N, S-CDs) produced by one-pot reflux treatment of C₃N₃S₃ with ethane diamine at a relatively low temperature (80 °C) show high fluorescence quantum yield about 30.4%, favorable biocompatibility, low-toxicity, strong resistance to photobleaching as well as good stability. The N, S-CDs as an effective temperature indicator exhibit good temperature dependent fluorescence with a sensational linear response from 20 to 80 °C. In addition, the obtained N, S-CDs show the high selectivity detection of tetracycline (TC) along with the detection limit as low as 3×10^-10 M and a wide linear range from 1.39×10^-5 to 1.39 ×10^-9 M. More importantly, the desired N, S-CDs display unambiguous bioimaging in the detections of intracellular temperature and antibiotic (TC), which could acquire satisfactory results.
