Robust Chemical Preservation of Digital Information on DNA in Silica with Error-Correcting Codes

Information, such as text printed on paper or images projected onto microfilm, can survive for over 500years. However, the storage of digital information for time frames exceeding 50years is challenging. Here we show that digital information can be stored on DNA and recovered without errors for considerably longer time frames. To allow for the perfect recovery of the information, we encapsulate the DNA in an inorganic matrix, and employ error-correcting codes to correct storage-related errors. Specifically, we translated 83kB of information to 4991 DNA segments, each 158nucleotides long, which were encapsulated in silica. Accelerated aging experiments were performed to measure DNA decay kinetics, which show that data can be archived on DNA for millennia under a wide range of conditions. The original information could be recovered error free, even after treating the DNA in silica at 70 degrees C for one week. This is thermally equivalent to storing information on DNA in central Europe for 2000years.
