| 英文摘要 | aqueous n-rich carbon dots (cds), prepared by the microwave-assisted pyrolysis method, are applied as a dual sensing platform for both the fluorescent and electrochemical detection of 2,4,6-trinitrotoluene (tnt). the fluorescent sensing platform is established on the strong tntamino interaction which can quench the photoluminescence of amino functionalized cds through charge transfer. the resultant linear detection ranges from 10 nm to 1.5 mu m with a fast response time of 30 s. glassy carbon electrode modified with cds exhibits a fine capability for tnt reduction with the linear range from 5 nm to 30 mu m, better than that obtained by the fluorescent method. moreover, the minimum distinguishable response concentration with respect to these two methods is down to the nanomolar level with a high specificity and sensitivity. |
