OPTICAL SENSOR AND MANUFACTURING METHOD THEREOF, AND DETECTION METHOD UTILIZING SAME

摘要

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.
