DNA origami snap-through switch enables durable nanoscale mechanical control
By
Friedrich C. Simmel
Summary
This article presents a scientific breakthrough in DNA nanotechnology: a high-endurance DNA origami snap-through switch that enables functional nanoscale control. The switch is mechanically bistable, allowing controlled and reversible transitions between distinct states at the molecular level. The research draws inspiration from bistable systems found in both macroscopic engineering and biological molecular switches, and demonstrates a DNA-based mechanism that can reliably toggle between functional states, offering potential applications in nanoscale computation, signal processing, and molecular machines.
