“…Z 0 is determined by the initial gap set point (4pA at −0.2V). This 20 pS conductance corresponds to a gap of about 2.5 nm (as determined using a 'chemical ruler' 16 ) so that the largest gap at which data were obtained from the Fab was about 3.5 nm. This corresponds to the shortest dimension of the Fab (it is about 6 nm long), suggesting that the Fab lies flat on the substrate and is unlikely to fluctuate into a vertical geometry.…”

Antibodies have two identical binding domains, and can therefore form a well-defined conducting bridge by binding a pair of electrodes functionalized with an epitope. The conductance measured between these two fixed points on the antibody does not change with the size of the electrode gap. A second conduction path is via one specific attachment to an epitope and a second non-specific attachment to the surface of the antibody. In this case, the conductance does change with gap size, yielding an estimated electronic decay length > 6nm, long enough that it is not possible to distinguish between an exponential or a hyperbolic distance dependence. This decay length is substantially greater than that measured for hopping transport in an organic molecular wire.
