Abstract:
A method of forming a laminar layered structure upon a surface of a substrate comprising:a) coating said substrate with an affinity coating,b) preparing a solution of a selected group of four DNA segments each formed from base molecules of adenine (A), guanine (G), cytosine (C), and thymine (T),c) bringing said surface into contact with said solution to thereby apply a layer of said solution to said surface,d) drying said layer to leave a lattice layer of cells formed by DNA segments upon said surface,e) preparing a liquid dispersion of inorganic particles coated with an organic stabilizer material, said inorganic particles having a substantially uniform diameter, not exceeding 20 nanometers,f) applying said liquid dispersion to said surface of said substrate to cause at least one of said inorganic particles coated with said organic stabilizer material to adhere to said surface within each cell of said lattice layer, said particles being maintained in a spaced-apart relationship upon said surface by said organic stabilizer material,wherein said synthetic DNA segments are produced with sequences permitting formation of a 2-dimensional lattice having a lattice spacing of less than 50 nm.
