At all but the very lowest frequencies, E-AB signaling is relatively unaffected by the ACV perturbation frequency used to interrogate the surface bound aptamers. This effect holds for both the cocaine (left) and thrombin (right) sensors and for both low (open circles) and high (filled circles) packing densities. Shown are data collected with low (1.6 × 1012 molecules/cm2) and high (4.3 × 1012 molecules/cm2) density cocaine sensors and low (5.8 × 1011 molecules/cm2) and high (1.3 × 1013 molecules/cm2) density thrombin sensors.
