Encoding Carbon Nanotubes with Tubular Nucleic Acids for Information Storage
Abstract
DNA has evolved to be a type of unparalleled material for storing and transmitting genetic information. Much recent attention has been drawn to translate the natural specificity of DNA hybridization reactions for information storage in vitro. In this work, we developed a new type of tubular nucleic acid (TNA) by condensing DNA chains on the surface of one-dimensional carbon nanotubes (CNTs). We find that DNA interacts with CNTs in a sequence-specific manner, resulting in different conformations including helix, i-motif, and G-quadruplex. Atomic force microscopic (AFM) imaging revealed that TNAs exhibit distinct patterns with characteristic height and distance that can be exploited for two-dimensional encoding on CNTs. We further demonstrate the use of TNA-CNT for information storage with visual output. This noncanonical, DNA hybridization-free strategy provides a new route to DNA-based data storage.

Condensing DNA strands onto carbon nanotubes creates height differences that are observable by AFM.
“AFM is also suitable to look at DNA positioned on other types of nanomaterials; for example, it was found that condensing DNA strands onto carbon nanotubes creates height differences that were observable by AFM (Figure 9B).”

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.
