A Proton‐Fuelled DNA Nanomachine
Abstract
Making DNA blink: A molecular machine based on the DNA i-motif structure is driven by changing pH (see picture). At pH 5, oligonucleotide X* folds into the i-motif (closed state), and complementary strand Y adopts a random-coil structure. At pH 8, X* unfolds and forms an extended duplex with Y. This reversible process can be monitored by means of a rhodamine green label (green circle), whose fluorescence is quenched by a dabcyl moiety (gray circle) in the closed but not in the open state.

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.
