NANO PARTICLE STRATIFICTION STRUCTURE USING SYNTHETIC DNA LATTICE

摘要

PROBLEM TO BE SOLVED: To form a stratification structure of nano-meter(nm) scale particles by placing a lattice-shaped lattice layer containing deoxyribo nucleic acid(DNA) so as to form a cell of the lattice layer on the surface of a substrate, and arranging a single particle in each cell. SOLUTION: A lattice constant of a stratification structure (a second lattice) of nano-meter scale particles is controlled by a lattice layer coincident in DNA. A DNA lattice (a first lattice) is manufactured using an automatic synthesizing method, this arrangement causes DNA to form a regular arrangement in an opening or a lattice site by self organization so as to include a specific nucleotide base arrangement. Then (a) a substrate 1 having a surface, (b) the lattice- shaped lattice layer containing a DNA segment arranged so as to form a cell of the lattice layer are arranged on the surface of the substrate 1, and (c) at least one particle 3 is placed in each cell. Thus, a stratification structure of nano-meter scale particles can be easily formed.
