TI  - Association interaction and voltammetric determination of 1-aminopyrene and 
      1-hydroxypyrene at cyclodextrin and DNA based electrochemical sensors.
PG  - 191-7
AB  - The aim of this work was voltammetric determination of 1-aminopyrene and 
      1-hydroxypyrene using carbon paste electrodes modified with cyclodextrin 
      derivatives and double stranded deoxyribonucleic acid (dsDNA). The detection 
      schemes based on a preconcentration and differential pulse voltammetric (DPV) 
      determination at beta-cyclodextrin and gamma-cyclodextrin modified carbon paste 
      electrode (beta-CD/CPE, gamma-CD/CPE), neutral beta-cyclodextrin polymer and 
      carboxymethyl-beta-cyclodextrin polymer modified screen-printed electrode 
      (beta-CDP/SPE, beta-CDPA/SPE) and dsDNA modified screen-printed electrode 
      (DNA/SPE) are proposed for the trace determination of studied analytes within the 
      concentration range from 2 x 10(-8) to 4 x 10(-7) mol dm(-3) and from 2 x 10(-7) 
      to 4 x 10(-6) mol dm(-3) with the limits of quantification down to 10(-8) mol 
      dm(-3). Depending on pH, 1-aminopyrene interacts with both surface attached CD 
      and DNA by electrostatic bonds and supramolecular complexation while 
      1-hydroxypyrene associates with the CD hosts via complexation. The 1-aminopyrene 
      interaction with dsDNA was confirmed by fluorimetric measurements in the solution 
      phase using a competing DNA-TO-PRO-3 dye complex. In addition, the effect of 
      temperature on this association was investigated using an electrically heated 
      DNA-modified carbon paste electrode (DNA/CPE).
