Abstract
A method of functionalization of a gate electrode of a field-effect transistor sensor includes forming a layer of biological recognition elements on a surface of said gate electrode, wherein said layer of biological recognition elements includes a self-assembled structure of one or more specific-binding-pair-forming substances (anti-hIg, anti-IgG, anti-IgM). The layer of biological recognition elements is treated with a solution containing a blocking agent to fill vacancies and prevent nonspecific binding in the self-assembled structure. One or more specific-binding-pair-forming substances immobilized in said layer of biological recognition elements are packed at a density of 0.1×10μmand 10×10μm, preferably between 1×10μmand 2×10μm.
