At elevated temperature an increase in sensitivity and selectivity as well as the minimization of electrode fouling could be observed. Surface modifications in the nano scale could further more improve the sensitivity. Procedures to detect genetically modified maize (MON 810) and PCR products were developed. The combination of DNA amplification and electrochemical detection was demonstrated.
