title: DNA hybridization "turns on" electro-catalysis at gold electrodes.
abstract: The efficiency of electro-catalysis occurring at DNA-modified gold electrodes is highly dependently on the density of DNA monolayers, as a result, DNA hybridization can "turn on" electro-catalysis by increasing the DNA surface density.
