摘要：
An electrochemical aptasensor was established for the fast and sensitive determination of tetracycline based on the synergistic effect of MoS 2 -thionine nanocomposite and aptamer. The glassy carbon electrode was coated with MoS 2 nanosheets of thionine to immobilize the tetracycline aptamer. In the absence of tetracycline, large quantities of thionin were loaded on the surface of the MoS 2 nanosheet to serve as the electrochemical probe. After tetracycline was added to the surface of the electrode, an aptamer analyte complex was produced on th...
