DNA Modified Screen-printed Carbon Electrodes as Chemical Sensors
Slovak University of Technology, Department of Analytical Chemistry, Bratislava 81237, Slovakia (Slovak Rep.)
Electrochemical DNA biosensors have found their permanent place among chemical sensors. The aim of this work is a development of simple (single-use) electrochemical sensors based on chemical interactions of the surface bound double stranded (ds) DNA. Carbon paste based screen-printed electrodes have been modified with the DNA layer and applied to the determination of various chemicals such as drugs and pollutants that bind to DNA, the detection of species leading to degradation of DNA and the investigation of antioxidants that prevent DNA towards its oxidative damage.
