Abstract: The invention relates to a preparation method and application of a sensing chip for detecting atrazine. A single-molecule alkyl chain layer is formed on a gold film of the surface plasma resonance sensing chip; atrazine molecularly imprinted polymer reaction solution is prepared by modifying the single-molecule alkyl chain layer; after soaking and eluting, holes which only respond to atrazine molecules are left in a molecularly imprinted polymer film, and the sensing chip for detecting the atrazin is obtained; when the sensing chip is used for detecting a sample by using the surface plasma resonance technology, the resonance angle changes after the sensing chip adsorbs the atrazine molecules in the sample, and the resonance angle change value and the sample concentration are in directly proportional linear relationship, so that the atrazine in the sample can be quantitatively detected on the basis of the change of the resonance angle. According to the preparation method and the application, the surface plasma resonance technology and the molecular imprinting technology are adopted to prepare the sensing chip, and the prepared sensing chip used for detecting the atrazine has the characteristics of sensitivity, rapidness, accuracy and simplicity.
