A Precisely Controlled DNA Biped Walking Device
Abstract
We present an experimental realization of a molecular walking motor built from DNA. The device consists of a biped and a well-defined track where it walks. Input DNA strands act as a convenient interface to allow precise control of the biped walking forward or backward. Psoralen molecules are attached to the ends of the feet in synthesis. When irradiated, the psoralen molecules cross-link strands covalently, allowing unambiguous determination of the state of the walker.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
