Abstract:
1. A method for producing a solid support comprising: a. forming a Diamond Like Carbon (DLC) layer having a thickness of 10 to 100 nm on a substrate; b. providing a positively charged electrostatic layer having a positively charged compound by depositing a compound having an unsubstituted or monosubstituted amino group and a carbon compound onto the DLC layer; wherein the positively charged electrostatic layer is formed by a polymer, and the positively charged electrostatic layer includes an amino group-containing compound that is polyallylamine; c. providing a chemically modifying layer on the positively charged electrostatic layer by introducing a functional group, said functional group includes a carboxyl group, which functional group is capable of covalently binding to a nucleic acid molecule, wherein said chemically modifying layer is a polyvalent carboxylic acid, and wherein the polyvalent carboxylic acid is a polyacrylic acid; and d. covalently binding the nucleic acid molecule to the chemically modifying layer.
