Abstract

Solid-state nanopores are powerful tools for reading the three-dimensional shape of molecules, allowing for the translation of molecular structure information into electric signals. Here, we show a high-resolution integrated nanopore system for identifying DNA nanostructures that has the capability of distinguishing attached short DNA hairpins with only a stem length difference of 8 bp along a DNA double strand named the DNA carrier. Using our platform, we can read up to 112 DNA hairpins with a separating distance of 114 bp attached on a DNA carrier that carries digital information. Our encoding strategy allows for the creation of a library of molecules with a size of up to 5 × 10 33 (2 112 ) that is only built from a few hundred types of base molecules for data storage and has the potential to be extended by linking multiple DNA carriers. Our platform provides a nanopore- and DNA nanostructure-based data storage method with convenient access and the potential for miniature-scale integration.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Information can be stored in the 3D structures of DNA assemblies instead of in the sequence, with readout relying on imaging techniques or single-molecule nanopore measurements.

    “Information can thus be stored in the 3D structures of these assemblies instead of in the sequence, with readout relying on imaging techniques, such as super resolution imaging,22 or using single-molecule nanopore measurements.23,25”

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.
