Title Method for immobilizing self-organizing material or fine particle on substrate, and substrate manufactured by using such method
Abstract (US7829546)
A method for immobilizing a self-organizing material or fine particles on a substrate, and a substrate whereupon the self-organizing material or the fine particles are immobilized.
More specifically, the method for immobilizing the fine particles including a nucleic acid (for instance, DNA or RNA) or a metal oxide on the substrate, and the substrate whereupon the nucleic acid (for example, DNA or RNA) or the metal oxide is immobilized.
Scope of claims [claim1]
1. A method for arranging fine particles on a substrate of metal-oxide, comprising the steps of: applying an acid solution to the substrate;
obtaining a mixed solution by mixing a solution containing the fine particles with a solution containing a self-organizing material;
applying the mixed solution to the substrate after removing the acid solution from the substrate; and
drying the mixed solution applied to the substrate with the self-organizing material still present on the substrate.
[claim2]
2. The method as set forth in claim 1, wherein the self-organizing material is a nucleic acid, a protein, an amino acid, a lipid, or a sugar.
[claim3]
3. The method as set forth in claim 1, wherein the metal oxide is Al2O3, ZnO, TiO2, SiO2, ZrO2, SrTiO2, LaAlO3, Y2O3, MgO, GGG, YIG, LiTaO, LiNbO, KTaO3, KNbO3, or NdGaO3.
[claim4]
4. The method as set forth in claim 1, wherein the fine particles comprise gold, silver, platinum, palladium, iridium, rhodium, osmium, ruthenium, nickel, cobalt, indium, copper, TiO2, or BaTiO3.
[claim5]
5. The method as set forth in claim 1, wherein the fine particles have a particle diameter in a range of 1 nm to 100 nm.
[claim6]
6. The method as set forth in claim 1, wherein the drying step is performed by blowing a dry inert gas or air.
