Abstract
In this paper, we present a new method for the detection of mercury (II) and glutathione using carbon dots as fluorescent sensor. The synthesized carbon dots have the advantages of simple manipulation, low cost and the high fluorescence quantum yield of them which was22.79%. The combination of mercury (II) and carbon dots caused the turn off of carbon dots fluorescence. With the reaction between mercury (II) and glutathione, the carbon dots were released and the fluorescence was turned on when the glutathione added. According to this, the carbon dots could be developed to detect mercury (II) and glutathione specifically, and the detection limit of mercury (II) is as low as 0.41μM.
