ABSTRACT:
An object of the present invention is to provide a simple biochemical sensor making use of the light interference effect of an optical film which is capable of measuring binding of biochemical substances at a high throughput. In the present invention, a solution containing samples18is passed through the sensor having probes17provided on an optical film with a refractive index of not less than 1.8 and not greater than 3 on a substrate, and binding of the probes17and samples18is detected from the change of intensity of the reflected light. This makes it possible to measure binding of biochemical substances at a high throughput with high precision.
