Advantages of downsizing electrochemical detection for DNA assays.

The article outlines the benefits of miniaturized amperometric electrochemical systems and their applicability in DNA/RNA assays. Emphasizing recent applications for micro-organisms, the advantages offered by miniatured electrochemical methods over the spectroscopic analyses are discussed. Information on how the diminishing size of detecting electrode improves oligonucleotides detection and molecular recognition techniques is presented.
