摘要: A method for purifying bioactive substances includes the steps of: causing a bioactive substance having histidine units to contact media, each constituted by a substrate, ligands which are physically attached to the surface of the substrate, and Cu(II) or Fe(II) metal ions which are covalently bonded to the ligands; causing the bioactive substance to covalently bond with the metal ions via the histidine units; and washing the media with an amount of 1 nmol/L to 10 mmol/L imidazole derivative solution 60 times the volume of the media or greater. In the case that the metal ions are Cu(II), the bioactive substance which has covalently bonded with the Cu(II) via the histidine units are recovered by one of a 10 mmol/L to 1 mol/L imidazole derivative solution and a 0.5 mmol/L to 5 mol/L EDTA solution.

摘要: A biosensor chip is constituted by: a substrate; a metal film which is physically attached to the substrate; and a self assembled monolayer constituted by alkyl chains, which is physically attached to the metal film. Ligands and at least one functional group, selected from a group consisting of a hydroxyl group, a carboxyl group, an alkoxy group, a methyl group, and hydrogen atoms are physically attached to the self assembled monolayer. The ratio between the total number of alkyl chains physically attached to the metal film and the number of alkyl chains which are covalently bonded with the ligands is within a range of 0.40 to 0.99.
