Abstract

In living systems, protonic and ionic currents are the basis for all information processing. As such, artificial devices based on protonic and ionic currents offer an exciting opportunity for bioelectronics. Proton transport in nature is important for ATP oxidative phosphorylation, the HCVN1 voltage gated proton channel, light activated proton pumping in bacteriorhodopsin, and the proton conducting single water file of the antibiotic gramicidin. In these systems, protons move along hydrogen bond networks formed by water and the hydrated biomolecules (proton wires). We have previously demonstrated complementary H+- and OH-- FETs with acid and base doped biopolymer proton wires and PdHx proton conducting contacts. Here, I will discuss proton-conducting devices based oh highly conductive proton wires that emulate brain synapses, display memristive behaviour, and are connected to form shift registries. Furthermore, I will present the integration of these devices with enzymatic logic gates for integrated biotic-abiotic protonic information processing. Preliminary results on using these devices to affect biological function will be discussed.
