RECOGNITION CHIP FOR TARGET SUBSTANCE, AND DETECTION METHOD AND DEVICE FOR THE SAME

摘要

A detection device comprising a substrate (103) comprising a plurality of objects (105) of which properties are changed due to the contact with a target substance, means for bringing the target substance into contact with the objects, and means (101, 107) for detecting a change in properties of the objects caused when the target substance is brought into contact with the objects, based on light output (106) when the objects are irradiated with light (102), wherein the plurality of the objects are located in the direction in which the light for irradiation travels, and the detecting means is means for detecting the change in the properties based on the summation of light output from the plurality of the objects upon irradiation with light.
