摘要: In this study, an electrogenerated chemiluminescence (ECL) sensing platform for carbofuran detection was constructed based on ECL energy transfer (ECRET) and carbon dot (C-dot)-tagged aptamers as the recognition element. Fullerene (C60)-loaded gold nanoparticles (C60-Au) were used as the energy donor, modified on a glassy carbon electrode. C-dot -tagged DNA aptamers were used as the receptor, and ECRET then occurred between C60-Au and C-dots. After accepting the energy, the C-dots acted as a signal indicator and showed decreased signal intensity in the presence of targets, which competitively bound to DNA aptamers and blocked energy transfer. Using this robust, straight-forward strategy, the sensor showed a linear ECL response to carbofuran at concentrations from 2.0 x 10(-11) mol L-1 to 8.0 x 10(-9) mol L-1. The detection limit of this assay was shown to be 8.8 x 10(-13) mol L-1. Thus, the sensing approach described in this study could be adapted for use in the detection of various pesticide residue targets. (C) 2016 Elsevier B.V. All rights reserved.
