Voltammetric properties and possibility of the determination of carcinogenic aminoderivatives of polycyclic aromatic hydrocarbons, namely 1- and 2-aminonaphthalene and 2-aminobiphenyl, have been investigated. Carbon paste electrodes (CPE) modified with monomeric α-, β- or γ-cyclodextrin and carbon-based screen-printed electrodes (SPE) surface-modified with a thin film of β-cyclodextrin (β-CDP) or carboxymethylated β-cyclodextrin (β-CDPA) condensation polymer were used for that purpose as simple electrochemical biosensors. Analytical procedure for the DPV determination of tested amines using these biosensors was proposed. Linear calibration plots within the concentration range of 2 × 10-8 -2 × 10-7 mol dm-3 and 2 × 10-7 -1 × 10-6 mol dm-3 with limits of quantification of the order of 10-9 mol dm-3 were obtained for the modified CPE and modified SPE.
