Abstract
A device, interface complex, diagnostic system, kit or method for use in binding analyte of interest, wherein immobilizing is on an aluminum oxide surface. An interface molecule is immobilized on the aluminum oxide surface. Attached to the interface molecule, is a cross linking agent for binding to the analyte, or a biomolecule specific to the analyte. The interface molecule includes a polypeptide having at least one carboxy rich domain providing at least 5 free carboxyl groups within a molecular volume of 2.2-25 nm, the free carboxyl groups being provided by amino acids containing two or more carboxyl groups, through which the interface molecule is immobilized to the aluminum oxide surface. The biomolecule may be covalently attached to the interface molecule, or the biomolecule may bean engineered antibody attached to the interface molecule through an antigenic determinant or through an Fc fragment.
