Abstract: Nowadays DNA-based biosensors represent powerful tools for the study of DNA sequence, DNA chemical interactions and damage. Among them, biosensors with an electrochemical signal transducer play the most important role. The performance of a biosensor strongly depends on the method of a biorecognition element being attached to the electrode. This review refers to polymer materials being used to create a DNA-electrode interface. The main terminology is given in Introduction followed by a description of polymers and polymer-based nanocomposites and their electrochemical properties. A comprehensive table reports examples of the electrochemical detection of DNA immobilized on the polymer matrix. Finally, a short survey is given.

Keywords: DNA biosensor - electrode - polymer - nanocomposite - surface modification
