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.
