Abstract
A data storage medium is disclosed comprising a dried product formed by drying a salt solution dried together with artificially synthesized DNA molecules encoding digital information. The cation in the salt may be calcium, magnesium, lanthanum, or another cation. The anion in the salt may be chloride, phosphate, or another anion. The DNA is protected from degradation by drying with the salt. Stored DNA may be freed from the salt for sequencing or other analysis by mixing the dried product with a chelator. The dry product formed from DNA and a salt may contain more than 30% DNA by weight and degrade at rates that are less than a third of rate at which untreated DNA degrades.
