COLORIMETRIC BIO SENSOR AND METHOD FOR DETECTING TARGET MATERIALS USING THEREOF

摘要

The color conversion biosensor of the present invention, and a method for detecting a target material using the same, include: a substrate surface-modified with a fast affinity functional group; a first plasmonic metal particle fixed to the metal affinity functional group; and a first aptamer that specifically binds to a target material bound to the first plasmonic metal particles, wherein when the sensor is exposed to a sample containing the target material, the target material is the first pressure It is characterized in that the plasmonic metal particles agglomerate through a binding reaction with the tamer to cause color conversion of the sensor.
