Abstract Based on the structural programmability and spatial addressability of DNA nanodevices, a target-triggered, enzyme-free 3D DNA walker, comprising of hairpin DNA assembled gold nanoparticles with a local catalytic hairpin assembly reaction, was developed for the highly sensitive detection of intracellular tumor-associated microRNAs. We construct a target-triggered, self-powered 3D DNA walker for achieving intracellular signal amplification and sensitive imaging analysis of microRNAs.
