Title:
エバネッセント波励起蛍光観察における背景光低減方法及び部材
Document Type and Number:
Japanese Patent JP4883398
Kind Code:
B2
Abstract:
In an evanescent wave exciting fluorescent observation, stray light arriving at a probe solution layer on an upper layer of a fixing region of molecules under examination in a reaction chamber is effectively absorbed by disposing a stray light absorptive region on a waveguide substrate, so that the stay light is suppressed to enter into the reaction chamber and the scattering stray light is suppressed to occur at an edge surface of the waveguide substrate made by applying a laser cutting process to the edge surface of the waveguide substrate on which light is incident. With the structure, critical background fluorescence at the evanescent wave exciting fluorescent observation is significantly reduced.
