Abstract: We have developed a piezoelectric sensor for the determination of atrazine. It is based on the modification of a molecularly imprinted film of TiO2 that was placed on a quartz crystal via a surface sol-gel process. The resulting sensor exhibits high selectivity for atrazine, a re-usability that is better than that of other sensors, a response time of 3 min, a wider linear range (0.0005-8 mM), and a lower detection limit (0.1 μM). The analytical application of the atrazine sensor confirms the feasibility of atrazine determination
