Abstract: One or more enzymes are used to repair damage in synthetic DNA molecules that encode digital information. The enzymes are included in a repair mixture containing one or more of DNA polymerase, DNA ligase, T4 Endonuclease, Endonuclease IV, Endonuclease VIII, and uracil glycosylase. The repair mixture may also contain one or more of a buffering solution, oxidized nicotinamide adenine dinucleotide (NAD+), and deoxyribose nucleoside triphosphates (dNTPs). The synthetic DNA molecules are incubated with the repair mixture for approximately four hours. Use of the repair solution allows recovery of the digital information from damaged DNA molecules.

Abstract: A data storage medium is disclosed comprising a two-dimensional (2D) support structure onto which artificially synthesized DNA molecules encoding digital information are placed and then covered with a protective layer. The 2D support structure is formed from a material such as metal foil, glass, or plastic. The 2D support structure may be functionalized with positively charged molecules to improve DNA adhesion. The DNA is protected from degradation by encapsulation in a protective layer of a non-reactive material such as silica or a thin layer of metal. A process for storing DNA on 2D support structures is also disclosed. Correlation of specific DNA molecules with a physical storage location on a 2D support structure provides geometric addressability for selective access to specific digital information.

Abstract: A data storage medium is disclosed comprising a substrate covered with alternating layers of a polycationic molecule and artificially synthesized DNA molecules encoding digital information. The magnetic substrate may be a metallic nanoparticle formed from a metal such as iron or cobalt. The polycationic molecule may be polyethyleneimine (PEI). The DNA is protected from degradation by encapsulation in silica. A process for stably storing DNA is also disclosed. Stored DNA may be freed from the silica for sequencing or other analysis by washing the silica-coated DNA with a buffered hydrogen fluoride solution. Storage densities of more than 7% DNA by weight are achieved on nanoparticles.

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.
