Patent number: 9291548Abstract: The invention makes it possible to measure binding of a biochemical substance with a high throughput and with high sensitivity using a small cell capable of being filled with a small amount of chemical solution. A space between a first substrate and a second substrate such that probes are immobilized on their mutually facing planes is used as a cell that houses a specimen solution. Light is irradiated from a first substrate side, and reflected light is subjected to spectroscopy. Binding of the target with the probe is detected by a wavelength shift in the refection spectrum.Type: GrantFiled: December 2, 2014Date of Patent: March 22, 2016Assignee: HITACHI, LTD.Inventors: Toru Fujimura, Kosuke Kuwabara, Tatsuro Ide
