“…The effective combination of the chemical molecules to be measured and optical fibers, as well we the corresponding Raman emission efficiency will affect the final detection effect, which is embodied in the performance parameters of the sensor. The stimulated luminescence characteristics (wavelength, frequency, and intensity) and the size of metal NPs (corresponding to stimulated fluorescence of different wavelengths) are all factors to be considered [ 64 ]. The enhancement of the optical signal and the interaction efficiency of chemical molecules are determined by the properties of metal NPs and functional films.…”

In recent years, surface plasmon resonance devices (SPR, or named plamonics) have attracted much more attention because of their great prospects in breaking through the optical diffraction limit and developing new photons and sensing devices. At the same time, the combination of SPR and optical fiber promotes the development of the compact micro-probes with high-performance and the integration of fiber and planar waveguide. Different from the long-range SPR of planar metal nano-films, the local-SPR (LSPR) effect can be excited by incident light on the surface of nano-scaled metal particles, resulting in local enhanced light field, i.e., optical hot spot. Metal nano-particles-modified optical fiber LSPR sensor has high sensitivity and compact structure, which can realize the real-time monitoring of physical parameters, environmental parameters (temperature, humidity), and biochemical molecules (pH value, gas-liquid concentration, protein molecules, viruses). In this paper, both fabrication and application of the metal nano-particles modified optical fiber LSPR sensor probe are reviewed, and its future development is predicted.

Raman scattering is a photon‐molecular interaction based on the kinetic modes of an analyte. It offers unique fingerprint‐type signals that allow molecular identification. A serious challenge frequently encountered in Raman measurements arises from the requirements of fast, real‐time remote sensing, fluorescence suppression, ultra‐micro concentration detection, small sample volumes and label‐free biological specimens. This review focuses on fibre‐optic probes for Raman spectroscopy, especially for enhanced sampling applications. It aims at providing an overview over contemporary technology and recent excellent researches, and helps identifying future developments necessary to bring the emerging technology to instrument manufacturers and end users. After a short introduction to surface‐enhanced Raman scattering technology, professional algorithms for design optimization of the fibre Raman probe will be discussed and general design considerations presented. Subsequently, various common geometries employed for enhanced Raman sampling are enumerated based on the types of waveguide fibres: multi‐fibre optodes, long‐pathlength capillary, microstructured photonic crystal fibre and other waveguide arrangements. Additionally, the relevant detection parameters are reviewed, such as target analyte, limit of detection, waveguide media and detection principle. The review also includes a brief summary of the advantages and limitations of various fibre Raman probes. Finally, the future work is discussed which will promote the reliability and the applicability of fibre enhanced Raman sensors. Copyright © 2017 John Wiley & Sons, Ltd.

“…These functional materials include nanoparticles [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ], nanowires [ 9 , 10 , 11 ], nanofilms [ 12 , 13 ] and 2-D materials [ 14 , 15 , 16 , 17 ]. For example, by coating plasmonic nanoparticles on the surface of a tapered optical fiber, compact (localized surface plasmon resonance) LSPR biosensors [ 4 , 5 , 6 , 7 ] and (surface-enhanced Raman scattering) SERS chemical sensors [ 18 ] can be achieved. Optical fibers decorated with Pd nanoparticles [ 3 ] or Pd nanofilms [ 13 ] can serve as reliable H 2 gas sensors.…”

Integration of functional nanomaterials with optical micro/nanofibers (OMNFs) can bring about novel optical properties and provide a versatile platform for various sensing applications. OMNFs as the key element, however, have seldom been investigated. Here, we focus on the optimization of fiber diameter by taking micro/nanofiber-based localized surface plasmon resonance sensors as a model. We systematically study the dependence of fiber diameter on the sensing performance of such sensors. Both theoretical and experimental results show that, by reducing fiber diameter, the refractive index sensitivity can be significantly increased. Then, we demonstrate the biosensing capability of the optimized sensor for streptavidin detection and achieve a detection limit of 1 pg/mL. Furthermore, the proposed theoretical model is applicable to other nanomaterials and OMNF-based sensing schemes for performance optimization.
