Abstract The present invention provides a surface plasmon-field enhanced fluorescence spectroscopic method in which a fluorescent substance is excited by means of surface plasmon resonance caused by the incidence of exciting light on an optical element, and fluorescence emitted from the fluorescent substance is measured, wherein the optical element is destaticized before the fluorescence is measured. This surface plasmon-field enhanced fluorescence spectroscopic method makes it possible to perform analysis having low optical noise, high sensitivity and high precision. La présente invention concerne un procédé spectroscopique de fluorescence améliorée par champ de plasmons de surface dans lequel une substance fluorescente est excitée au moyen d'une résonance de plasmons de surface provoquée par l'incidence d'une lumière d'excitation sur un élément optique, et la fluorescence émise par la substance fluorescente est mesurée, dans lequel l'élément optique est électrostatiquement neutralisé avant que la fluorescence soit mesurée. Le procédé spectroscopique de fluorescence améliorée par champ de plasmons de surface permet d'effectuer une analyse ayant un faible bruit optique, une sensibilité élevée et une précision élevée. 本発明は、光学素子に励起光を入射することにより生じる表面プラズモン共鳴により蛍光物質を励起して、前記蛍光物質から放出される蛍光の測定を行う表面プラズモン励起増強蛍光測定において、前記蛍光の測定を行う前に、前記光学素子の除電を行う表面プラズモン励起増強蛍光測定法である。本発明の表面プラズモン励起増強蛍光測定法は、光学ノイズが低く、高感度かつ高精度な分析が可能である。
