  • HIGH-SENSITIVITY LATERAL FLOW IMMUNOASSAY STRIP BASED ON SURFACE-ENHANCED RAMAN SCATTERING AND DETECTION METHOD USING THE SAME
    Publication number: 20230251202
    Abstract: The present disclosure relates to a surface-enhanced Raman scattering (SERS) lateral flow immunoassay strip containing: a sample pad into which a sample containing a target material is introduced; a conjugate pad containing a hollow metal nanoprobe for surface-enhanced Raman scattering, on which an antibody that can be coupled to the target material and a Raman marker are immobilized; and a detection pad including a detection region to which a secondary antibody that can be coupled to the target material coupled to the hollow metal nanoprobe is immobilized. Use of the SERS-based lateral flow immunoassay strip according to the present disclosure enables high-sensitivity quantitative analysis and qualitative analysis of the target material from Raman signal measurement depending on the concentration of the target material.
