Description
Summary:Proton conduction is essential in biological systems. Oxidative phosphorylation in mitochondria, proton pumping in bacteriorhodopsin, and uncoupling membrane potentials by the antibiotic Gramicidin are examples. In these systems, H + hop along chains of hydrogen bonds between water molecules and hydrophilic residues – proton wires. These wires also support the transport of OH − as proton holes. Discriminating between H + and OH − transport has been elusive. Here, H + and OH − transport is achieved in polysaccharide- based proton wires and devices. A H + - OH − junction with rectifying behaviour and H + -type and OH − -type complementary field effect transistors are demonstrated. We describe these devices with a model that relates H + and OH − to electron and hole transport in semiconductors. In turn, the model developed for these devices may provide additional insights into proton conduction in biological systems.
