Toehold-mediated DNA logic gates based on host–guest DNA-GNPs

Chem. Commun., 2014
A simple, toehold-mediated two-way input DNA machine has been developed. Utilizing symmetric and asymmetric protector sequences, INH, XOR logic gates and a half-subtractor are designed based on this two-way structure.

Co‐Localization‐Gated Multivalent DNA Logic Gate for Programmable Cell Recognition

Angewandte Chemie International Edition
ABSTRACT Achieving precise and robust cell‐surface recognition in complex biological environments is challenging due to inherent trade‐offs in affinity, specificity, and off‐target binding. Herein, we present a programmable molecular device that integrates Boolean logic computation with spatial confinement to overcome these ...

Time-Gated FRET and DNA-Based Photonic Molecular Logic Gates: AND, OR, NAND, and NOR

ACS Sensors, 2017
Molecular logic devices (MLDs) constructed from DNA are promising for applications in bioanalysis, computing, and other applications requiring Boolean logic. These MLDs accept oligonucleotide inputs and generate fluorescence output through changes in structure.

Logic Gate Based on Circular DNA Structure with Strand Displacement

2016
In this work, we fabricated two logic gates based on circular DNA structure – XOR gate and AND gate calculation model with the principle of complementary base pairing and the technology of fluorescence labeling. Whereafter, we constructed a simple half-adder model based on the two logic gates. This model is simple, but it can realize more complex logic

Automatic Design of DNA Logic Gates Based on Kinetic Simulation

2009
Recently, DNA logic gates and DNA machines have been developed using only a simple complementary base pairing of DNA, that is, hybridization and branch migration. Because such reaction systems have been designed by trial and error, it has been difficult to design a complex system and to correctly verify the reaction.

A quantum logic gate in the DNA deoxyribose moiety

Quantum Effects and Measurement Techniques in Biology and Biophotonics
The deoxyribose moiety of a nucleotide in the DNA molecule can act as a quantumlogic gate, in which the enantiomeric shift between the C2-endo and C3-endo conformations of each nucleotide, occurs within a logically and thermodynamically reversible situation of electron spin qubits, that are coherently held within the topologically insulating DNA ...
