Detection of Benzimidazole toxins by molecularly imprinted polymer based on polyaniline

چکیده مقاله

In present study sensing behavior of molecular imprinting polymer (MIP) based on polyaniline as a monomer in contrast with agronomy fungicides as like as Carbendazim and Tiophanate methyl as a sample via measurment of electrical conductivity by using a four-probe method was investigated. Molecular imprinting has proved to be an effective technique for the creation of recognition sites on a polymer scaffold. Polyaniline as a conductive polymer has been used in many application like conducting dyes, chemical and gas sensors and it is one of the best choices for this technique. Molecularly imprinted polymers (MIPs) are synthetic materials that mimic antibodies and widely used in pharmaceutical, medical and chemical applications such as chemical sensors. Analyte concentration and polymer response time are the sensing properties studied in this work. The selectivity of molecular imprinting polymer as compared with those of analyte molecular with similar structure was investigated. In all cases, the conductivity of molecular imprinting polymer in comparison with the molecular non-imprinting polymer (NIP) was noticeable. This is due to analyte effect on polymer structure.
