Condensing member to be used for the surface plasmon enhanced fluorescence sensor and the surface plasmon enhanced fluorescence sensor

摘要

Since it can be prevented that there is no the value of S / N is reduced collection efficiency falls, between the light detecting means and the reaction layer becomes wider, without the need for focusing to a lens In addition, manufacturing costs and an object thereof is to provide a condensing member for use in surface plasmon enhanced fluorescence sensor and the surface plasmon enhanced fluorescence sensor with reduced. By irradiating the excitation light to one side surface of the metal thin film, which enhances the electric field of the metal thin film, the light collector therefor, the fluorescent material excited reaction layer formed on the other side of the metal film, A condensing member used for the surface plasmon enhanced fluorescence sensor that was to be detected by the light detecting means enhanced fluorescence Thus, the condensing member, between said light detecting means and said reaction layer and a total reflection function member to be those that are arranged, and condensed fluorescence is the excitation, to reach the light detecting means in the total reflection condition of the fluorescence.
