Screen printed electrodes(SPE)
are disposable, low-cost and portable devices that include a miniaturized display of the working, reference and counter electrodes; based on conductive substrates like carbon nano allotropes (e.g. graphite, graphene) and metals (e.g. Au, Ag, Pt). This configuration is optimized to work with micro-volumes of samples. Their range of applications includes electrochemical analysis in environmental, clinical and agri-food fields.
