Fiber-Optic Sensors Based on Surface Plasmon Resonance: A Comprehensive Review

Review of surface plasmon resonance and localized surface plasmon resonance sensor

“…Optical fiber SPR sensors have been studied extensively based on their unique advantages such as miniaturization, high spatial resolution, and capability of on-line distributed measurement and remote sensing in dangerous environments [30,31]. We designed and fabricated a novel wavelength-modulated optical fiber SPR sensor by using an ultra-thin dielectric film of MgF 2 as the modulated and protected layer, the influences of the dielectric film on the sensitivity and shape of the resonant dip are investigated which are significant to the SPR fiber sensor.…”

Use of Thin Sectioning (Nanoskiving) to Fabricate Nanostructures for Electronic and Optical Applications

“…[59] There is, thus, a major challenge in optics to which nanoskiving seems particularly (perhaps uniquely) well-suited-modifying the cleaved facets of optical fibers with arrays of nanostructures. The ability to control the emission from fibers using filters or polarizers, or the fabrication of sensors for in situ, label-free detection of chemical or biological analytes using either SERS [148] or LSPRs, [149] are possible applications of modified optical fibers. [150] Attachment of plasmonic arrays to (or formation on) the cleaved facets of fibers is not straightforward by conventional means, however.…”

“…The energy of the LSPR is a function of the size and shape of the particle, and its dielectric environment. [118] Applications of plasmonic nanoparticles include optical filters; [120,121] substrates for optical detection of chemical and biological analytes using LSPRs [122] or surface-enhanced Raman scattering (SERS); [123][124][125] substrates for enhanced luminosity; [126] materials to augment absorption in thin-film photovoltaic devices; [127] metamaterials [7,128] with negative magnetic permeabilities [129] and refractive indices; [130] and materials for perfect lenses, [131] and invisibility cloaking. [132] The most sophisticated arrays of plasmonic structures are fabricated using EBL, [133] FIB, [130] or direct laser writing.…”

An Overview of Analytical Techniques Employed to Evidence Drug-DNA Interactions. Applications to the Design of Genosensors

“…These plasmons are supported by metal-dielectric interfaces and then are referred to as surface plasmons. Direct light cannot excite surface plasmons at a metal-dielectric interface, because the propagation constant of surface plasmons in metal is greater than the one of the light wave in the dielectric medium (Sharma et al, 2007). To solve this problem, surface plasmons are generated by coupling them to an evanescent field.…”
