The mercaptopropionic acid self-assembly on the gold plate electrode surface at different times, the change of the peak current (ip) in the cyclic voltammetry curve can be observed.Through the different tendency of the frequency of the quartz crystal gold electrode before and after the assembly of mercaptopropionic acid Self-assembly results and observed mercaptopropionic acid shedding at a certain potential.Using the electrostatic attraction between the positive and negative charges between mercaptopropionic acid and trichosanthin, the trichosanthin was assembled on the surface of the gold electrode after the saturation adsorption of mercaptopropionic acid, Cyclic voltammetry was used to characterize the electrochemical properties of the self assembled electrode
