“…Haynes et al introduced a large variety of nanoparticle structures and well-ordered 2D nanoparticle arrays using nanosphere lithography (NSL), and the sensitivities of each feature were probed using an LSPR sensor [ 89 ]. Tanaka et al utilized high-refractive-index silver nanoparticle sheets on a metal substrate for a high-sensitivity SPR sensor [ 90 ]. In that study, the angular shifts increased with the number of Ag nanoparticle sheet layers, improving the angular sensitivity compared with a conventional SPR sensor.…”

From active developments and applications of various devices to acquire outside and inside information and to operate based on feedback from that information, the sensor market is growing rapidly. In accordance to this trend, the surface plasmon resonance (SPR) sensor, an optical sensor, has been actively developed for high-sensitivity real-time detection. In this study, the fundamentals of SPR sensors and recent approaches for enhancing sensing performance are reported. In the section on the fundamentals of SPR sensors, a brief description of surface plasmon phenomena, SPR, SPR-based sensing applications, and several configuration types of SPR sensors are introduced. In addition, advanced nanotechnology- and nanofabrication-based techniques for improving the sensing performance of SPR sensors are proposed: (1) localized SPR (LSPR) using nanostructures or nanoparticles; (2) long-range SPR (LRSPR); and (3) double-metal-layer SPR sensors for additional performance improvements. Consequently, a high-sensitivity, high-biocompatibility SPR sensor method is suggested. Moreover, we briefly describe issues (miniaturization and communication technology integration) for future SPR sensors.

“…Unresolved issues in the optical characterization of nanofluids are the effective refractive index at high concentrations [ 4 ] and the change of optical property during the solidification of nanofluids [ 3 ]. The approach of higher refractive index prism, tunable SPR resonance wavelength, and enhanced sensitivity is expected to address these issues [ 18 , 19 , 20 ].…”

“…It can provide real-time and full-field imaging, which is beneficial to monitor near-surface transport or optical property changes such as concentration, temperature, salinity, and effective refractive index [ 3 , 4 , 5 , 6 , 7 ], which is not possible with existing techniques. This technique can be more powerful if its sensitivity can be increased in order to monitor the fine ion change in bio applications through grating structure [ 18 ] and high refractive index sheets [ 19 ]. Another idea is to combine the exotic optical properties of hyperbolic metamaterials (HMM) with its SPR resonance dispersion controllability to improve sensitivity [ 20 ].…”

Nanophotonic technique has been attracting much attention in applications of nano-bio-chemical sensing and energy conversion of solar energy harvesting and enhanced energy transfer. One approach for nano-bio-chemical sensing is surface plasmon resonance (SPR) imaging, which can detect the material properties, such as density, ion concentration, temperature, and effective refractive index in high sensitivity, label-free, and real-time under ambient conditions. Recent study shows that SPR can successfully detect the concentration variation of nanofluids during evaporation-induced self-assembly process. Spoof surface plasmon resonance based on multilayer metallo-dielectric hyperbolic metamaterials demonstrate SPR dispersion control, which can be combined with SPR imaging, to characterize high refractive index materials because of its exotic optical properties. Furthermore, nano-biophotonics could enable innovative energy conversion such as the increase of absorption and emission efficiency and the perfect absorption. Localized SPR using metal nanoparticles shows highly enhanced absorption in solar energy harvesting. Three-dimensional hyperbolic metamaterial cavity nanostructure shows enhanced spontaneous emission. Recently ultrathin film perfect absorber is demonstrated with the film thickness as low as ~1/50th of the operating wavelength using epsilon-near-zero (ENZ) phenomena at the wavelength close to SPR. It is expected to provide a breakthrough in sensing and energy conversion applications using the exotic optical properties based on the nanophotonic technique.

“…Various fabrication methods for fiber-based RI sensors have been reported in the literature [1], including surface plasmon resonance (SPR) [2,3], evanescent field [4], fiber gratings [5,6], and optical fiber interferometry [7]. However, the sensitivity of the traditional sensing techniques needs to be improved in practical applications.…”

This paper presents a high sensitivity liquid refractive index (RI) sensor based on lossy mode resonance (LMR) effect. The Dshaped fibers coated with nanosized titanium dioxide (TiO 2 ) thin film as a sensing head were submerged into different refractive index solutions. The variations in the optical spectrum of the proposed RI sensor with different refractive index solutions were measured. The LMR resonance peaks were used to determine the wavelength shifts with different refractive index solutions. The results show that the optical spectrum peaks shifted towards the longer wavelength side with increasing the refractive index. For the proposed fiber sensing head with a polishing residual thickness of 72 m, the maximum shift of the absorption peak was 264 nm. The sensitivity of the proposed RI sensor was 4122 nm/RIU for the refractive index range from 1.333 to 1.398.
