DNA data storage on two-dimensional support material

A system comprising:

• a two-dimensional (2D) support structure having disposed thereon a first DNA at a first position and a second DNA at a second position, the 2D support structure having a first surface and a second surface opposite the first surface, and a silica coating encapsulating the first DNA and the second DNA;
• a controlled fluid-delivery system configured to deposit an etching buffer that dissolves the silica coating at the first position and not at the second position responsive to identification of the first position by a lookup record;
• and
• electronic media containing the lookup record, wherein the lookup record contains identification of first information encoded by the first DNA linked to the first position on the 2D support structure and second information encoded by the second DNA linked to the second position on the 2D support structure, and wherein the lookup record is implemented in a look-up table that stores the first information linked to the first position and the second information linked to the second position.
