| 英文摘要 | nitrogen and sulfur co-doped carbon dots (n,s/c-dots) with high fluorescence quantum yields (flqy, 25%) was successfully synthesized by a one-step microwave-assisted method. in comparison with nitrogen doped c-dots (n/c-dots) prepared using the same method, the resulting n,s/c-dots featured small particle size, uniform surface state, insensitive fl properties to excitation wavelengths and environmental conditions, negligible cytotoxicity and excellent biocompatibility. simultaneous doping of n and s effectively promoted electron-transfer and coordination interaction between n,s/c-dots and hg2+. thus, when used as fluorescence probe for hg2+ label-free detection, the resulting n,s/c-dots showed good detection sensitivity and ion selectivity. the limit of detection was 2 mu m; among 15 metal ions investigated, only fe3+ showed interference to the hg2+ detection. fortunately, this interference could be effectively shielded using a chelating agent sodium hexametaphoshpate. the applicability of n,s/c-dots as fluorescence probe for hg2+ detection in lake water and tap water was demonstrated. finally, based on its favorable features of negligible cytotoxicity and excellent biocompatibility, the n,s/c-dots were successfully applied to probe hg2+ in living cells, which broaden its application in biological system.
