Abstract: An optical sensor includes an input part, a fixing part, and a determining part. The input part is provided on the upper side of the sensor. The fixing part on which a carrier is disposed is provided below the input part. The carrier has an acceptor that reacts with an analyte contained in the sample and is fixed on the carrier. The determining part includes a first metal layer, a second metal layer, and a hollow area. The first metal layer is configured to receive an electromagnetic wave. The second metal layer faces the first metal layer. The hollow area is sandwiched between the first metal layer and the second metal layer. The input part, the fixing part, and the hollow area form a part of a passage where the sample flows from the input part to the hollow area.

Abstract: A flow channel device includes a flow channel section and an introduction channel section. The flow channel section includes a flow channel in which a detection object flows and a wall surface surrounding the flow channel. The introduction channel section includes an introduction channel having a first end connected to the flow channel and a second end connected to an introduction port, and a wall surface surrounding the introduction channel. At least a part of the wall surface surrounding the introduction channel is a curved surface protruding toward the introduction channel.

Abstract: An optical sensor is configured to be used with trappers specifically bound to an object substance to detect whether the object substance exists or not in a specimen. The optical sensor includes a first metal layer made of gold having a lower surface and an upper surface which is configured to have an electromagnetic wave supplied thereto, and a second layer made of gold having an upper surface facing the lower surface of the first metal layer. A hollow area configured to be filled with the specimen is provided between the first metal layer and the second metal layer. The trappers are physically bonded to at least one of a lower side of the first metal layer and an upper side of the second metal layer. The thickness of the first metal layer is not smaller than 5 nm and not larger than 30 nm. The optical sensor has a small size and a simple structure.
