Abstract:
PURPOSE: A method for manufacturing a bio sensor platform in which an olfactory receptor protein is pattern-evaporated, the bio sensor platform manufactured by the same, a field-effect transistor including the same, and a bio sensor are provided to introduce a functional stage by chemically processing a surface of a patterned nano structure and to function as an olfactory receptor, thereby obtaining improved selectivity and sensitivity for detecting smell substances. CONSTITUTION: A method for manufacturing a bio sensor platform in which an olfactory receptor protein is pattern-evaporated is as follows. A substrate surface is patterned with photoresist. A self-assembled monolayer of polyethylene glycol is pattern-formed on the patterned substrate surface. The photoresist is eliminated from the substrate in which the self-assembled monolayer of the polyethylene glycol is formed. A nano structure is evaporated in a portion of the substrate in which the self-assembled monolayer of the polyethylene glycol is not formed so that the polyethylene glycol and nano structure manufacture a pattern-evaporated substrate. The nano structure evaporated in the substrate is chemically processed, thereby having an amine. A surface of the nano structure is activated. The olfactory receptor protein is fixed to the activated nano structure.
