Abstract

Recent years have witnessed the exponential growth of information, calling for the development of new storage media. DNA provides an attractive alternative for data storage due to its high physical density, reproducibility, and excellent durability that have been tested by nature. Rapid progress has been made during the past decade by exploiting artificially designed DNA materials for data storage. Herein, recent advances of DNA‐based encoding, writing, storage, retrieving, reading, and decoding for data storage are summarized. In addition to encoding with nucleic acid sequences, different forms of data storage strategies using DNA nanostructures are also highlighted. Also, in vivo DNA data storage, especially with the use of clustered regularly interspaced short palindromic repeat–Cas systems, is discussed. The challenges and opportunities for the development and application of DNA‐based data storage are presented.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • DNA has a theoretical data density of 6 bits for every 1 nm of polymer, or ∼4.5 × 10^7 GB/g, which is orders of magnitude higher than the densities achievable using traditional devices.

    “On the basis of its physical dimensions, DNA has a theoretical data density of 6 bits for every 1 nm of polymer, or ∼4.5 × 107 GB/g,6 which is orders of magnitude higher than the densities achievable using traditional devices.7,8”
  • The current writing speed for DNA archives is in the order of kilobytes/second, thus a reading/writing cycle has a significant cost in terms of time.

    “The current writing speed for DNA archives is in the order of kilobytes/second, thus a reading/writing cycle has a significant cost in terms of time.”
  • The current record for DNA digital data storage is still around 200 MB, with single synthesis runs lasting about 24 h.

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.
