| 英文摘要 | Room temperature phosphorescence (RTP) property of Mn-doped ZnS quantum dots (QDs) was explored to develop a novel method for selective detection of lead cation. The influence factors such as buffer kinds and their concentration, the concentration of Mn-doped ZnS QDs solution, reaction time and coexisting substances were studied. It was found that under optimized conditions, i.e. 10 mmol/L Tris-HCl buffer at pH 7.4 and 2 min reaction time, the relative RTP intensity of the Mn-doped ZnS QDs was quenched linearly by lead cation in the concentration range from 0.25 to 1000 mu mol/L, and the limit of detection was 0.04 mu mol/L (8.3 mu g Pb/L). This method was also applied to measure lead cation in biosamples using a high-throughput 96 well plate with a wide linear range, simpleness, rapidness, high sensitivity and selectivity, and cost effectiveness. The RTP was quenched linearly by lead cation in human plasma in the concentration range from 5 to 1000 mu mol/L, and the limit of detection was 0. 48 mu mol/L (Pb 99 mu g/L), respectively. |
