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 an affinity functional group; A first plasmonic metal particle immobilized on the metal affinity functional group; And a first aptamer that specifically binds to a target material bound to the first plasmonic metal particle, and when the sensor is exposed to a sample containing the target material, the target material is It is characterized in that the color conversion of the sensor occurs due to the aggregation of the plasmonic metal particles through a coupling reaction with the timer.
