Dopamine (DA) is an important catecholamine neurotransmitter and its abnormal concentration closely related to diseases such as hypertension, Parkinson’s disease schizophrenia. Due the advantages of high sensitivity fast response for electrochemiluminescence (ECL), developing ECL sensors detecting DA was very critical in clinical diagnosis. resonance energy transfer (ECL-RET) effective signaling mechanism. However, shortage highly efficient ECL-RET pairs impeded development sensors. Herein, methyl-modified perylene diimide derivative (PDI-CH3) self-assembly nanorod materials luminophores CuO nanomaterials acceptors were integrated into nanocomposites. An obvious found PDI-CH3/CuO After nanocomposites treated with DA, a large increase intensity observed. Then, taken platform detect DA. This sensor exhibited linear from 10−12 M 10−8 limit detection 0.20 pM. Compared other detection, constructed higher sensitivity. In addition, novel this work showed good practicability human serum sample.
