SENSOR CHIP FOR BIOSENSOR, BIOSENSOR AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a sensor chip for a biosensor, the biosensor using the sensor chip and a method for manufacturing of the biosensor whereby a material required for the manufacturing can be readily obtained and ligands (molecule discrimination elements) can be fixed with high density. SOLUTION: A self-organizing single molecule film layer made from straight hydrophobic molecules having a functional group connectable to a metallic thin film at one end is formed on the metallic thin film of a light-permeable carrier body as a first layer. A plane single molecule film layer made from amphipathic molecules wherein a hydrophobic part is oriented on the self- organizing single molecule film layer is provided to the surface of the first layer as a second layer for chemical connection with ligands (molecule discrimination elements). Thus, there are provided a sensor chip for a biosensor, the biosensor for surface plasmon resonance constituted such that the ligands are chemically connected to the surface of the sensor chip and a method for manufacturing of the biosensor.
