Abstract：The effect of carbon quantum dots on the electrogenerated chemiluminescence (ECL) energy transfer sensing system for the determination of DNA was investigated. The results showed that the signal- to-noise ratio of luminol-crystal violet ECL system was increased and its reproducibility was improved by the addition of carbon quantum dots. The conditions of the detection of DNA were optimized. Under optimal conditions, the linear range for the determination of target DNA was 1.0×10-11～1.0×10-7 mol/L, the correlation coefficient was 0.9881 and the detection limit was 4.0×10-12 mol/L. The possible interaction mechanism between DNA and carbon quantum dots was also discussed. This method was convenient and showed high sensitivity.
