ABSTRACT

The present study is focused on the detection sensitivity enhancement of our previously developed amplitude-sensitive paired surface plasma waves biosensor in combination with gold nanoparticles (GNP). The approach enables improvement of the sensitivity of real-time detection by three orders of magnitude.

Keywords: Gold nanoparticles, Surface Plasmon Resonance (SPR), Biosensor, Heterodyne.
