Preparation of electro-polymerization molecularly imprinted polymer hollow channel paper device and application of paper device in instant pesticide residue detection

The invention discloses preparation of an electro-polymerization molecularly imprinted polymer hollow channel paper device and an application of the paper device in instant pesticide residue detection. A wax printing pattern and a hollow channel cutting pattern are designed on a computer by utilizing AdobeIllustratorCS4 software; a hydrophobic area can be printed by a wax printing machine; an entrance, an exit and a hollow channel are cut by a laser cutting machine; a carbon working electrode, a carbon counter electrode and an Ag/AgCl reference electrode are printed on a working area by the screen printing technique; molecularly imprinted polymers are electro-polymerized on the working electrode by a cyclic voltammetry method; a plurality of pieces of prepared filter paper are stacked between glass sheets sequentially to prepare the electro-polymerization molecularly imprinted polymer hollow channel paper device, and the electrode in the device is connected with an electrochemical workstation to realize instant detection of pesticide residues.
