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 ...

Molecular Chains: Arranging and Programming Logic Gates
Nano Letters, 2020One particularly fascinating vision for charge-operated devices is the controlled assembly of structures from single surface-deposited molecules. Here, we report on the assembly of linear clusters that consist of phthalocyanine (H2Pc) molecules on a Ag(111) surface.

An OR logic gate based on two molecular beacons
Molecular BioSystems, 2012Abstract Design of elementary molecular logic gates is the key and the fundamental of performing complicated Boolean calculations. Herein, we report a strategy for constructing a DNA-based OR gate by using the mechanism of sequence recognition and the principle of fluorescence resonance energy transfer (FRET). In this system, the gate

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

Electronically Configurable Molecular-Based Logic Gates
Science, 1999Logic gates were fabricated from an array of configurable switches, each consisting of a monolayer of redox-active rotaxanes sandwiched between metal electrodes. The switches were read by monitoring current flow at reducing voltages. In the “closed” state, current flow was dominated by resonant tunneling through the electronic states of the molecules ...

Nanocell logic gates for molecular computing
IEEE Transactions on Nanotechnology, 2002Molecular electronics seeks to build electrical devices to implement computation - logic and memory - using individual or small collections of molecules. These devices have the potential to reduce device size and fabrication costs, by several orders of magnitude, relative to conventional CMOS. However, the construction of a practical molecular computer

A DNA based molecular logic gate capable of a variety of logical operations
Natural Computing, 2013In this paper we report on a module in the RTRACS (Reverse-transcription and TRanscription-based Autonomous Computing System) molecular computing system, constructed with DNA, RNA and enzymes. The module is a 2-input logic gate that receives input and produces output in the form of RNA molecules.
