A novel strategy for imprinting of ethyl nitrate molecules at the surface of functionalized multiwalled carbon nanotubes/polyethyleneimine(FUN-MWCNTs/PEI) was developed to prepare a highly selective ethyl nitrate-imprinted electrochemical sensor.The samples were characterized by Scanning electron microscope(TEM),Fourier transform infrared spectroscopy(FT-IR) and Electrochemical experiments.The electrochemical characteristics of the imprinted FUN-MWCNTs/PEI-MIPs sensor were investigated by cyclic voltammetry...
