Abstract
An apparatus includes a substrate and a plurality of DNA oligomers in contact with a top surface of the substrate. The substrate is a polar ferroelectric or a polar compound semiconductor.
Claims20
An apparatus, comprising:
- a substrate that is a polar ferroelectric or a polar compound semiconductor, the substrate having a top surface and being hydrophilic;
- and
- a two-dimensional array of DNA tiles being in contact with exposed portions of said top surface, each DNA tile of the array having sticky ends of single stranded DNA hybridized to sticky ends of single stranded DNA of others of the DNA tiles of the array some of the DNA tiles being patterned with metal, quantum dots, or dye molecules;
- and wherein the substrate comprises an optical waveguide, the DNA tiles being adjacent to a side surface of the optical waveguide.
