SURFACE PLASMON RESONANCE SENSOR |
摘要 |
PROBLEM TO BE SOLVED: To provide a surface plasmon resonance sensor capable of providing a plurality of measurement regions by solving a problem that a conventional surface plasmon resonance sensor has only one measurement region. SOLUTION: This surface plasmon resonance sensor is so structured that a metal thin film is formed on the back face of a prism, a sample solution is directly brought into contact with the surface of the metal thin film, light is entered into the prism in a condition where the light is totally reflected by the interface between the metal thin film and the sample solution, and the state of a substance in the sample solution can be analyzed based on the reflected light. The sensor characteristically includes a continuous sample solution feeding passage bent so as to form at least two measurement regions intercrossing with the surface of the metal thin film formed on the prism.
