Energy transduction and signal averaging of fluctuating electric fields by a single protein ion channel

Abstract: 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. … Show more

“…Figure shows the basic scheme for the electrical transduction of a fluctuating signal of zero‐average into a net current that allows charging the load capacitor to significant voltages . The process is experimentally robust and can be scaled up by using multipore membranes instead of single‐nanofluidic diodes .…”

“…The hybrid network can be described theoretically by means of equivalent electrical circuits that permit to simulate the system response for each practical design . We will focus here on the case of polymeric nanopores but the concepts developed can also be implemented using solid‐state pores and ion channels …”
