Charge transport in purple membrane monolayers: A sequential tunneling approach
, 2011 Current voltage (I-V) characteristics in proteins can be sensitive to conformational change induced by an external stimulus (photon, odour, etc.). This sensitivity can be used in medical and industrial applications besides shedding new light in the ...

Photochemical reaction of bacteriorhodopsin
FEBS Letters, 1976 Halobacterium halobium utilizes light both as a stimulus for phototaxis [l] and as an energy source for creating a proton gradient across the cell membrane which in turn produces ATP [2] . The photoreceptive pigment of this bacterium was first investigated by Oesterhelt and Stoeckenius [3] who showed that it is the only protein lying in so-called ...

Aggregate, Volume 7, Issue 6, June 2026.This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

Investigations on the electrical current-voltage response in protein light receptors
, 2014 We report a theoretical/computational approach for modeling the current-voltage characteristics of sensing proteins. The modeling is applied to a couple of transmembrane proteins, bacteriorhodopsin and proteorhodopsin, sensitive to visible light and ...

An Artificial Molecular Pump Powered by Light
Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.A minimal rotaxane‐based supramolecular system functions as a light‐powered molecular pump, capturing macrocycles from solution and concentrating them within an intramolecular compartment. Repeated azobenzene photoisomerization modulates the binding and kinetic barriers of threading and shuttling, generating a photon‐driven energy ratchet that sustains
