1. A method for manufacturing a surface-enhanced Raman scattering (SERS)-based substrate for detecting a target substance, comprising:
a step of forming a primary capture structure with a target substance and a bioreceptor bound by immersing a bioreceptor-attached substrate in a sample solution comprising a target substance;
a step of disposing the substrate with the primary capture structure formed in a centrifuge tube and adding a solution comprising metal nanoparticles into the centrifuge tube; and
a step of forming a secondary capture structure directly coating the metal nanoparticles on a surface of the target substance by operating the centrifuge tube.
