| Summary: | This paper presents a novel U-shaped fiber surface-enhanced Raman scattering (SERS) spectra probe with high-performance remote sensing based on femtosecond laser ablation and deposition of photoreduced silver nanoparticles. As the width of the U-shaped structure is around 12 <inline-formula> <tex-math notation="LaTeX">$\mu\text{m}$</tex-math></inline-formula>, the sensitivity is enhanced about four times more than that of a single-endface-based fiber SERS probe. The experiment results show that there is a nonlinear relationship between the SERS signal and the width of the U-shaped structure, whereas the SERS signal is sharply decreased with the increasing width of the U-shape. Our U-shaped fiber SERS probe shows a feasible method for high-performance, real-time, and remote measurement of the SERS signal in biochemical analysis. |
