Molecular interaction detector and molecule recovery device using the same

摘要

In a molecular interaction detector, a noble-metal free-electron thin film is formed on a substrate. Styrene-made nanoparticles are adsorbed onto the thin film surface. Another noble-metal free-electron thin film is formed on upper-half surfaces of the nanoparticles and is modified by an organic linker molecule. The organic linker molecule has a linear or branched chemical structure including a functional group capable of being fixed to the surface of the noble-metal free-electron thin film with a linear chain made of 1 to 5 atoms. A detergent is used in a mobile phase. Deposition of materials having no relation with the measurement onto a sensor can be avoided in the molecular interaction detector.
