SENSOR, DETECTION METHOD, DETECTION SYSTEM, AND DETECTION DEVICE

摘要

In one form, this sensor has a bonding part (240) which bonds with a second substance (220) which has a greater molecular weight than a first substance (210). Further, in one form, a sensor has a base (10) having on the surface a bonding part (240) for detecting whether the first substance (210) is contained in a sample which is in contact with both the second substance (220) and an aptamer (230), said aptamer (230) having a first binding site (231) which bonds with the first substance (210) and a second binding site (232) which bonds with the second substance (220), and binding with either the first substance (210) or the second substance (220).
