Of the multiple areas of applications of DNA nanotechnology, stimuli-responsive nanodevices have emerged as an elite branch of research owing to the advantages of molecular programmability of DNA structures and stimuli-responsiveness of motifs and DNA itself. These classes of devices present multiples areas to explore for basic and applied science using dynamic DNA nanotechnology. Herein, we take the stake in the recent progress of this fast-growing sub-area of DNA nanotechnology. We discuss different stimuli, motifs, scaffolds, and mechanisms of stimuli-responsive behaviours of DNA nanodevices with appropriate examples. Similarly, we present a multitude of biological applications that have been explored using DNA nanodevices, such as biosensing, in vivo pH-mapping, drug delivery, and therapy. We conclude by discussing the challenges and opportunities as well as future prospects of this emerging research area within DNA nanotechnology.

Abstract Biosensor design is important to bioanalysis yet challenged by the restricted target accessibility at the biomolecule-surface (bio-surface). The last two decades have witnessed the appearance of various “art-like” DNA nanostructures in one, two, or three dimensions, and DNA nanostructures have attracted tremendous attention for applications in diagnosis and therapy due to their unique properties (e.g., mechanical flexibility, programmable control over their shape and size, easy and high-yield preparation, precise spatial addressability and biocompatibility). DNA nanotechnology is capable of providing an effective approach to control the surface functionality, thereby increasing the molecular recognition ability at the biosurface. Herein, we present a critical review of recent progress in the development of DNA nanostructures in one, two and three dimensions and highlight their biological applications including diagnostics and therapeutics. We hope that this review provides a guideline for bio-surface engineering with DNA nanostructures.
