Researchers demonstrated a proof-of-principle way to encode information in the proportions of isotopologues—molecules with the same chemical structure but different isotopes—and read those proportions using mass spectrometry. Their analysis predicted more than 130 million distinguishable mixture combinations, but that is a theoretical count, not a demonstrated storage capacity or a measure of data per gram.
How information is encoded and read
The method stores a code in the composition of a molecular mixture. Its components are isotopologues of the same small molecule: they share a structure but differ in how many hydrogen atoms have been replaced by deuterium, a heavier isotope of hydrogen. The relative amounts of those components define the mixture’s code.

To read a mixture, the researchers measured its mass-spectrometric fingerprint. The spectrum reflects the mixture’s isotopic composition, allowing the team to infer which components were present. This is a chemical-analysis approach, not a digital storage device that can be read with ordinary computer hardware.
What the study tested
In the 2024 Chemical Science study, Petra Sőregi, Márton Zwillinger, Lajos Vágó, Márton Csékei, and András Kotschy used an aminoquinoline carboxylic acid derivative with 24 non-labile hydrogen positions available for deuterium substitution. They prepared components spanning D0 through D24, where the number indicates how many positions were replaced, and characterized the actual isotopologue composition of those materials. The publisher’s record identifies the work as an Edge Article in Chemical Science, volume 15, pages 14938–14945, first published on 22 August 2024.
#1 Best Overall
Rather than testing every possible mixture, the researchers selected binary, ternary, and quaternary mixtures predicted to have highly similar fingerprints. They prepared and measured those mixtures and reported unambiguous identification of their actual compositions in these proof-of-principle tests. The study also explored changing deuteration composition to make fingerprints more distinctive and adding covalent tags while retaining the code. The primary article includes supporting data in its supplementary information and links calculation code for mass-spectral fingerprints.
What “more than 130 million” means
The headline figure is the authors’ theoretical estimate of more than 130 million distinguishable combinations when using up to ten components from the prepared isotopologue set. It counts candidate mixture combinations under the study’s analysis; it does not mean the researchers stored and retrieved 130 million records.
Rank #2
That distinction matters: the experiments established recovery for selected difficult mixtures, while the larger number comes from theoretical analysis. The paper does not report an operational archive, commercial storage capacity, or a measured density such as bits per gram. The Chemistry World report used the broader framing of high-density information storage, but the study’s result is best understood as a proposed encoding space supported by limited experimental tests.

The theoretical collection assumes idealized isotopologue components. In practice, a synthesized component is not necessarily a perfectly pure molecule with exactly one deuteration count; it can contain a distribution of deuteration states. That spread can blur the intended mixture composition and make different fingerprints more alike.
Rank #3
- Component purity: A distribution of isotopologues in a prepared component reduces the distinction between idealized code choices.
- Fingerprint overlap: If two mixtures produce similar spectra, reliably telling them apart becomes harder.
- Measurement and synthesis: Encoding depends on making the chemical components and reading them with mass spectrometry, both specialist laboratory processes.
Consequently, the selected successful tests demonstrate feasibility under the tested conditions; they do not establish large-scale practical capacity, long-term retention, or universal resistance to counterfeiting.

This is a research method, not a ready-to-use alternative to hard drives, flash memory, or other commercial storage. Its distinctive idea is to encode information in mixture proportions rather than solely in a molecule’s sequence, then recover it from a mass spectrum. Assessing it as a practical storage system would require evidence on reliable capacity at scale, reproducible synthesis and readout, retention over time, and protection against ambiguous or imitated fingerprints—questions this study does not settle.
