| 英文摘要 | We develop a novel kind of nitrogen-doped carbon dots (N-CDs) with unprecedented properties through hydrothermal treatment of soluble starch and ethylenediamine. Such N-CDs can emit two strong emission peaks at about 450 nm and 540 nm under a single-wavelength ultraviolet-light excitation. The intensity ratios of the two emission peaks are influenced by pH values, leading to the change of fluorescent colours, which can be utilized to detect solution pH by the change of fluorescent colours. Most importantly, N-CDs can act as fluorescence probes for labelling cell nucleus of BHK cells selectively, indicating that the as-prepared N-CDs have specific targeting towards nucleus cells. In addition, the fluorescence intensity can be quenched by Fe3+ ion and restored by ascorbic acid effectively. The detection limits for Fe3+ and AA were 84.9 nM and 62.1 nM, respectively.
