Biological surfaces are known to be capable of retaining protons and facilitating their lateral
diffusion. Since the surface dynamically exchanges protons with the bulk, the proton …

It has been shown with lipid layers and more recently with purple membranes that protons
have slow surface-to-bulk transfer. This results in long-range proton lateral conduction along …

Recent experiments suggest that protons can travel along biological membranes up to tens
of micrometers, but the mechanism of transport is unknown. To explain such a long-range …

Proton diffusion (PD) across biological membranes is a fundamental process in many
biological systems, and much experimental and theoretical effort has been employed for …

Proton diffusion along the surface of a planar bilayer lipid membrane was measured by
means of acid/base injection with a micropipette and recording of the kinetics of …

Proton transfer over large distances is critical to biology, particularly so for cellular
bioenergetics. Transmembrane proton pumps such as cytochrome oxidase generate a …

Translocation of protons across biological membranes is carried out by special membrane
proteins, proton pumps. Surprisingly, the turnover rate of some proton pumps, such as …

Proton diffusion along biological membranes is vitally important for cellular energetics. Here
we extended previous time-resolved fluorescence measurements to study the time and …

The thin water layer, as found in chloroplast or mitochondria, is confined between low
dielectric amphypathic surfaces a few nm apart. The physical properties of this mesoscopic …

For H+ transport between protein pumps, lateral diffusion along membrane surfaces
represents the most efficient pathway. Along lipid bilayers, we measured a diffusion …
