Gold nanoparticles (Au-NPs) and silver nanoparticles (Ag-NPs) are of particular interest in DNA sensors and immunosensors due to their advantageous properties, such as hydrophilicity, standard fabrication methods, excellent biocompatibility, unique characteristics in the conjugation with biological recognition elements, and multiplex capacity for signal transducer. Therefore, a large number of published methods use Au- or Ag-NPs in DNA [16,17,18] protein [19] and even cell [20] electrochemical detection besides optical detections like ICP-MS [21] or their use as ELISA enhancer [22].
