Abstract

This paper proposes Fiber-Optic Localized Surface Plasmon Resonance (FO LSPR) sensor combined with micro fluidic channel, which enables the continuous supply of fluid for bio-reaction. The proposed method can prevent the degradation of the sensing characteristics due to the change of measurement condition. The feasibility of the FO LSPR sensor with micro fluidic channel is proved by Computational Fluid Dynamics simulation (CFD). Also, the proposed method has been evidenced by measuring the output intensity of the FO LSPR sensor at various refractive index solutions. Finally, Prostate Specific Antigen (PSA) immunoassay was measured to verify the possibility of the fabricated sensor system as a biosensor.
