We demonstrate the electrical rectification and signal averaging of fluctuating signals using a biological
nanostructure in aqueous solution: a single protein ion channel inserted in the lipid bilayer characteristic
of cell membranes. The conversion of oscillating, zero time-average potentials into directional currents
permits charging of a load capacitor to significant steady-state voltages within a few minutes in the case
of the outer membrane porin F (OmpF) protein, a bacterial channel of Escherichia coli. The experiments
and simulations show signal averaging effects at a more fundamental level than the traditional cell and
tissue scales, which are characterized by ensembles of many ion channels operating simultaneously. The
results also suggest signal transduction schemes with bio-electronic interfaces and ionic circuits where
soft matter nanodiodes can be coupled to conventional electronic elements. [-]
