A DNA Based Molecular Logic Gate Capable of a Variety of Logical Operations

2012
In this paper we report on a module in the RTRACS 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. Each of the two input molecules is chosen from a set of two, and the logic gate produces an output molecule for each of the four ...

Nuclease-containing media for resettable operation of DNA logic gates

Chemical Communications, 2015
A system which enables DNA logic gates to respond multiple times to the addition of oligonucleotide inputs was developed. This system does not require any operator action to achieve reset.

DNAzyme-Based Logic Gate-Mediated DNA Self-Assembly

Nano Letters, 2015
Controlling DNA self-assembly processes using rationally designed logic gates is a major goal of DNA-based nanotechnology and programming. Such controls could facilitate the hierarchical engineering of complex nanopatterns responding to various molecular triggers or inputs.

Aptamer-Binding Directed DNA Origami Pattern for Logic Gates

ACS Applied Materials & Interfaces, 2016
In this study, an aptamer-substrate strategy is introduced to control programmable DNA origami pattern. Combined with DNA aptamer-substrate binding and DNAzyme-cutting, small DNA tiles were specifically controlled to fill into the predesigned DNA origami frame.

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.

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
