A Label-Free and Anti-Interference Dual-Channel SPR Fiber Optic Sensor With Self-Compensation for Biomarker Detection

In this work, we report a self-compensating, label-free, and anti-interference surface plasmon resonance (SPR) fiber biosensor based on a cascaded U-shaped multimode fiber and a single-mode fiber and both coated with gold film. In the traditional dual-channel SPR sensor structure, in order to obtain...
