Abstract: Atrazine is a widely used herbicide. The electrochemical sensing of atrazine was performed by the detection of its reductive current. In order to make the sensing system smaller and simpler, a gold electrode chip (detection area: 1.8 x 0.6 mm) was prepared and modified with an atrazine imprinted polymer layer, as the recognition element for atrazine. An atrazine sensing chip modified with molecularly imprinted polymer (MIP) layer was fabricated by spin-coating in this study. Using the atrazine-sensing chip, a cathodic current of atrazine was observed and the reductive current depended on the concentration of atrazine below 20 μM. The detection limit of the sensor was 50 T nM (11 ppb). The atrazine-sensing chip was more selective to atrazine than other herbicides such as simazine, ametryn and MCC
