Abstract
The present invention relates to an immunochromatographic detection sensor comprising optical waveguides and a detection method using the same, and more particularly, to an immunochromatographic detection sensor comprising optical waveguides, in which the optical waveguides are provided under the membrane, probe beams transmitted through the optical waveguide maximize the interaction frequency between evanescent wave generated on the surface of optical waveguide and the colored conjugate in the band formed on the membrane, and thus the absorbance signal from the colored conjugate is greatly amplified to improve the sample detection sensitivity, and a detection method using the same.
