Molecular Mechanisms of Cyclic Nucleotide-Gated Ion Channel Gating
Journal of Genetics and Genomics, 2007Cyclic nucleotide-gated ion channels (CNGs) are distributed most widely in the neuronal cell. Great progress has been made in molecular mechanisms of CNG channel gating in the recent years. Results of many experiments have indicated that the stoichiometry and assembly of CNG channels affect their property and gating.

Molecular Orbital Gates for Plasmon Excitation
Nano Letters, 2013Future combinations of plasmonics with nanometer-sized electronic circuits require strategies to control the electrical excitation of plasmons at the length scale of individual molecules. A unique tool to study the electrical plasmon excitation with ultimate resolution is scanning tunneling microscopy (STM). Inelastic tunnel processes generate plasmons

Chemistry – An Asian Journal, 2011
AbstractChemists are now able to emulate the ideas and instruments of mathematics and computer science with molecules. The integration of molecular logic gates into small arrays has been a growth area during the last few years. The design principles underlying a collection of these cases are examined. Some of these computing molecules are applicable in

A Parallel Electromagnetic Molecular Logic Gate
Journal of the American Chemical Society, 2005A theoretical study of transport through a three-terminal molecular ring in the presence of a magnetic field is presented. The physical principles necessary to achieve logic operations based on the Aharonov-Bohm effect are discussed. We show that a proper combination of a gate potential and a realistic magnetic field can be used to obtain parallel ...

Edge-on Gating Effect in Molecular Wires
Nano Letters, 2015This work demonstrates edge-on chemical gating effect in molecular wires utilizing the pyridinoparacyclophane (PC) moiety as the gate. Different substituents with varied electronic demands are attached to the gate to simulate the effect of varying gating voltages similar to that in field-effect transistor (FET).

Design of a Gated Molecular Proton Channel
Angewandte Chemie International Edition, 2010The generation of an electrochemical pH gradient across biological membranes using energy from photosynthesis and respiration provides the universal driving force in cells for the production of adenosine triphosphate (ATP), the energy unit of life. Creating such an electrochemical potential requires the transportation of protons against a thermodynamic

Controlling the dynamics of molecular encapsulation and gating
Chem. Soc. Rev., 2011This critical review describes mechanisms by which guest molecules enter and depart molecular capsules. The discussion focuses on presenting gated molecular encapsulation, i.e., trapping and releasing of guest molecules at rates that are controlled by conformational changes in the host's structure. Developing quantitative rules that describe the gating

Electrostatic Gate Control in Molecular Transistors
Topics in Current Chemistry, 2018Molecular transistors, in which single molecules serve as active channel components in a three-terminal device geometry, constitute the building blocks of molecular scale electronic circuits. To demonstrate such devices, a gate electrode has been incorporated in several test beds of molecular electronics.

Molecular mechanisms of gated ion channels
Bioelectrochemistry and Bioenergetics, 1986Abstract Ion channels form the basis for intercellular communication in biological systems. With the advent of cloning techniques, it is now possible to sequence the proteins that form such channels. The acetylcholine receptor, for example, which consists of five subunits, and the voltage gated sodium channel have been completely sequenced by Noda et
