表面プラズモン共鳴センサを用いた間接競合法によるフルフラールの検出

抄録

In this study, we tried to detect furfural, which is one of the body odor compounds using anti-furfural monoclonal antibody and surface plasmon resonance (SPR) sensor with indirect competitive method. 5-formyl-2-furancarboxylic acid (FFC), 4-carboxybenzaldehyde, 3-(5-oxooxolan-2-yl) propanoic acid were immobilized on sensor chips modified with a self-assembled monolayer containing oligo (ethylene glycol). As a result, 190 ppb limit of detection for furfural was obtained using SPR sensor with indirect competitive method and the FFC-modified sensor chip.
