1. A method for analysis, comprising:
binding analytes (4) in a sample to biomolecules (3) attached to a solid surface of a substrate (1); and
detecting the analytes bound to the biomolecules; wherein:
the biomolecules (3) are attached directly in an oriented manner to the substrate together with biomolecule-repellent molecules (5); and
the biomolecule-repellent molecules are covalently attached to the substrate through functional groups and are self-assembled on the surface to cover the surface between the biomolecules (3) to prevent non-specific binding of analytes (4) and other biomolecules.
