Title:
センサユニット
Document Type and Number:
Japanese Patent JP4485959
Kind Code:
B2
Abstract:
A surface plasmon resonance sensor unit includes a prism. A thin film has a first surface and a sensing surface. The first surface overlies the prism to constitute a thin film/prism interface. The sensing surface immobilizes a sample in sample fluid. Illuminating light is applied to the interface in a form satisfying a condition for total internal reflection, to create attenuated total reflection in the illuminating light reflected by the interface. An angle of incidence of the illuminating light upon the attenuated total reflection is changed upon (bio)chemical reaction of the sample on the sensing surface. The sensor unit includes an enclosing cover, secured to the prism, for covering the sensing surface. A lower recess is formed in the prism, and positioned at the sensing surface. The lower recess constitutes a flow channel for flow of the sample fluid on the sensing surface.
