A log structured content addressable deduplicated data storage system may be used to store deduplicated data. An embodiment of the present disclosure provides a touch stack-up structure that comprises sequentially forming a patterned transparent conductive layer, a first transparent insulation layer with low refractive index, a second transparent insulation layer with high refractive index, and an optical clear adhesive on a transparent substrate. This process includes an optional conversion step that replaces non-standard nucleobase pairs with standard nucleobase pairs, generating large synthetic DNA molecules containing only natural nucleotides. The set of data elements is stored at the software distribution server.
