Different platforms for DNA electrochemistry. Single Au electrodes can be set up on either an Au on mica surface (left) or using a rod electrode (right). A multiplex platform (center) (Pheeney et al., 2013; Slinker et al., 2010) with 16-electrodes separated into four quadrants can also be used to assay multiple DNA substrates on a single surface, with replicates for each condition. Platforms are shown from the top (above) and from the side (below) with components of the setup.
