Electrochemical Indicators for DNA Electroanalysis

Electrochemical redox compounds, which can interact or bind with different affinities to single and double stranded DNA and thus are referred to as electrochemical hybridization indicators, represent a powerful and, along with this, simple tool for electrochemical genetic analysis. In this paper, general tendencies and recent advances in this field, including the modes of DNA-redox indicators interactions, approaches for their electrochemical analysis, and applications in electrochemical DNA assays are overviewed. This is a critical mini-review with 122 references.
