Abstract

A novel bio-detecting chip configuration based on the fiber surface plasmon enhancement mechanism is proposed and analyzed. Our improvement is proposing to couple the specialized shell-isolated gold nanoparticles into the sensing region of the opened fiber-integrated microfluidic chip, and achieving drastic surface plasmon enhancement by employing the guided optical mode. Simulation shows that the optical intensity distribution near the surface of exposed fiber hole is enhanced drastically, which could be beneficial to the fluorescence or Raman enhancement. Our work could contribute to searching novel microfluidic chip based bio-detecting methods such as for tracing poisonous and harmful substances detection.
