In the past decades, electrochemical DNA sensors have attracted substantial attention owing to their high sensitivity, rapid response, portability, and low cost. Proper electrode surface modification is a principal stage in DNA sensors elaboration. Along with reliable immobilization of single-stranded DNA (ss-DNA) probes, a key requirement to surface coatings is to prevent nonspecific adsorption. However, modification of electrodes may lead to diminishing of electroactive properties. In this work we present conductive polymer material with improved electroactive properties and electrochemical DNA-sensor based on it.
