<abstract xmlns="http://www.w3.org/1999/xhtml"> Alachlor (ALA) has been widely used in agriculture and may act as a carcinogen and an environmental estrogen. The present work deals with chemical modification of boron-doped diamond electrode (BDDE) by guanosine monophosphate (GMP) and its study in the presence of ALA. Cyclic voltammetry and electrochemical impedance spektroscopy in the presence of the redox indicator 1 × 10-3 mol/L [Fe(CN)6]3-/4- together with differential pulse voltammetry of the nucleotide base were explored to test effects of GMP immobilization time, the pesticide concentrations and incubation time in the pesticide solution. It was found that GMP layer on the BDDE surface is distorted after incubation in the ALA solution.</abstract>
