“…Due to this limitation, instead of adopting the LSPR of nanostructured graphene, hybrid nanostructures consisting of metallic NPs and graphene (or its derivatives) have been an alternative research direction in sensing applications [930][931][932][933]. For example, an LSPR gas sensor was fabricated by depositing rGO flakes on a monolayer of Au NPs [933].…”

Optical sensors are widely used for refractive index measurement in chemical, biomedical and food processing industries. Due to specific field distribution of the resonances excited, optical sensors provide high sensitivity to ambient refractive index variations. The sensitivity of optical sensor is highly dependent on material and structure of the sensor. Here, we review six major categories of optical refractive index sensors using plasmonic and photonic structures: (i) metal-based propagating plasmonic eigenwave structures, (ii) metal-based localized plasmonic eigenmode structures, (iii) dielectric-based propagating photonic eigenwave structures, (iv) dielectric-based localized photonic eigenmode structures, (v) advanced hybrid structures, and (vi) 2D material integrated structures. Representative configurations working in the wavelength range of 400−2000 nm will be selected and compared in terms of bulk refractive index sensitivities, figure of merits and working wavelengths. A technology map is established in order to define the standard and development trend for optical refractive index sensors.

“…Metal NPs can also be modified on the surface of materials with specific structures before they are modified onto fiber structures. Graphene provides an ideal two-dimensional planar substrate and binding sites for NPs [ 128 ]. The three-dimensional functional structure was constructed by stacking multilayer 2D planar graphene [ 129 ].…”

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.

“…Nayak et al developed different refractive index sensors using graphene oxide encapsulated gold nanoparticles (GOE-AuNPs) [ 97 ] and graphene oxide-encapsulated silver nanoparticles (GOE-AgNPs) [ 98 ] as LSPR generating materials. The main benefits of encapsulating the nanoparticles in GO are the control of the inter-particle distance, preventing aggregation, the enhancement of the colloidal stability and the prevention of the oxidation of the AgNPs, avoiding their direct contact with the aqueous medium.…”

Graphene and its derivatives have become the most explored materials since Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The exceptional properties of graphene have attracted the attention of the scientific community from different research fields, generating high impact not only in scientific journals, but also in general-interest newspapers. Optical fibre sensing is one of the many fields that can benefit from the use of these new materials, combining the amazing morphological, chemical, optical and electrical features of graphene with the advantages that optical fibre offers over other sensing strategies. In this document, a review of the current state of the art for optical fibre sensors based on graphene materials is presented.
