Abstract: An electrochemical sensor for detection of mancozeb from soil and vegetable sample using molecularly imprinted star polymer modified with iron oxide nanoparticles (SPIONs) is described in this work. We have prepared SPIONS by hydrothermal method and modified with vinyl silane to introduce double bond at their surface. The vinyl group modified SPIONs were used to form mancozeb imprinted star polymer (ISP). The ISPs have specific recognition ability high adsorption capacity towards their template molecule and could be easily extracted from complex matrices using a simple magnet. The prepared polymer was well characterized by field emissive scanning electron microscopy (FE-SEM). Under the optimum condition, the prepared sensor shows good response for mancozeb in the range of 5.96 to 222.39 μg L-1 (detection limit=0.98 μg L-1). The proposed sensors have highly selective for detection of mancozeb in soil and vegetable samples also
