An enzyme-free and DNA-based Feynman gate for logically reversible operation

Chem Commun (Camb). 2015 Jun 28;51(51):10284-6. doi: 10.1039/c5cc02865e.

Abstract

A logically reversible Feynman gate was successfully realized under enzyme-free conditions by integrating graphene oxide and DNA for the first time. The gate has a one-to-one mapping function to identify inputs from the corresponding outputs. This type of reversible logic gate may have great potential applications in information processing and biosensing systems.
