1. A method of detecting bioproducts characterized by comprising the steps of:

  • (a) immobilizing receptors onto a localized surface plasmon resonance (LSPR) sensor comprised of gold nanoparticles, the surface of which is modified with an organic adsorbent, and a cover glass where the gold nanoparticles are fixed;

    (b) flowing a target material on the sensor having the immobilized receptors and(c) determining light-scattering spectra by using dark-field microscopy and a resonant Rayleigh scattering micro-spectroscopy system and analyzing mobility of the maximum wavelength.
