Observation of molecular orbital gating

Nature, 2009
The control of charge transport in an active electronic device depends intimately on the modulation of the internal charge density by an external node. For example, a field-effect transistor relies on the gated electrostatic modulation of the channel charge produced by changing the relative position of the conduction and valence bands with respect to ...

Molecular Optoelectronic Gates

Journal of the American Chemical Society, 1996
In this paper we describe molecular devices where an electronic energy transfer process is selectively gated by one-electron alteration of the redox state of one spatially isolated pigment in a multipigment array. We demonstrate gating of a photonic signal in a molecular device via a spatially isolated redox switch.

Molecular Mechanisms of Cyclic Nucleotide-Gated Ion Channel Gating

Journal of Genetics and Genomics, 2007
Cyclic 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, 2013
Future 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

Design of a Gated Molecular Proton Channel

Angewandte Chemie International Edition, 2010
The 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

Microfluidic AND gate design for molecular communication

Proceedings of the 7th ACM International Conference on Nanoscale Computing and Communication, 2020
The design of components with molecular communication (MC) functionalities can bring new opportunities to facilitate emerging applications in fields from personal healthcare to modern industry. In this paper, we propose the microfluidic AND gate design, and we also establish a general mathematical framework to theoretically characterize this ...

Controlling the dynamics of molecular encapsulation and gating

Chem. Soc. Rev., 2011
This 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
