An enzyme-free DNA walker that moves on the surface of functionalized magnetic microparticles and its biosensing analysis

Author affiliations

Abstract

An enzyme-free stochastic DNA walker propelled by a single catalytic or double catalytic DNA assembly has been constructed. The application of the proposed DNA walking biosensor was successfully expanded to the detection of DNA and the enzymatic activity of T4 polynucleotide kinase.
