In this mode redox probes to produce detectable signals are no longer covalently labeled onto the aptamers in this mode. Probes dissolved in electrolyte solution can interact with aptamers immobilized on an electrode via (1) electrostatic repel-lence (for negatively charged probes), (2) electrostatic adsorption (for positively charged probes), and (3) intercalation (for DNA intercalators).
