“…Another way for improvement is utilization of the magnetic layers in the plasmonic structure to measure a magnetooptical response instead of the reflection one 16 17 18 19 20 21 . In this respect, the transverse magnetooptical Kerr effect (TMOKE) is usually considered.…”

“…Throughout the paper, when speaking about the quality factor we mean the ratio of the full width at half maximum (FWHM) of the resonance to its central wavelength. The recently demonstrated MO sensors 16 17 18 19 20 21 still have rather poor quality factor of both optical and magnetooptical resonances, but nevertheless they often show the resolution limit several times higher compared to the conventional SPR ones.…”

Currently, sensors invade into our everyday life to bring higher life standards, excellent medical diagnostic and efficient security. Plasmonic biosensors demonstrate an outstanding performance ranking themselves among best candidates for different applications. However, their sensitivity is still limited that prevents further expansion. Here we present a novel concept of magnetoplasmonic sensor with ultranarrow resonances and high sensitivity. Our approach is based on the combination of a specially designed one-dimensional photonic crystal and a ferromagnetic layer to realize ultralong-range propagating magnetoplasmons and to detect alteration of the environment refractive index via observation of the modifications in the Transversal Magnetooptical Kerr Effect spectrum. The fabrication of such a structure is relatively easy in comparison with e.g. nanopatterned samples. The fabricated heterostructure shows extremely sharp (angular width of 0.06°) surface plasmon resonance and even sharper magnetoplasmonic resonance (angular width is 0.02°). It corresponds to the propagation length as large as 106 μm which is record for magnetoplasmons and promising for magneto-optical interferometry and plasmonic circuitry as well as magnetic field sensing. The magnitude of the Kerr effect of 11% is achieved which allows for detection limit of 1∙10−6. The prospects of further increase of the sensitivity of this approach are discussed.

“…In one hand, the dielectric properties of the oxide affect the SPR Au response, and in the other hand its magnetic properties can be used for separation and/or pre-concentration of the analytes before SERS application. FANSs, in majority, and AFNSs, in minority have been thus developed for such a purpose [ 107 , 108 , 109 , 110 , 111 ]. They possess the advantages of convenient binding to biomolecules and easy separation using a magnetic field.…”

Iron Oxide and Gold Based Magneto-Plasmonic Nanostructures for Medical Applications: A Review

Iron oxide and gold-based magneto-plasmonic nanostructures exhibit remarkable optical and superparamagnetic properties originating from their two different components. As a consequence, they have improved and broadened the application potential of nanomaterials in medicine. They can be used as multifunctional nanoprobes for magneto-plasmonic heating as well as for magnetic and optical imaging. They can also be used for magnetically assisted optical biosensing, to detect extreme traces of targeted bioanalytes. This review introduces the previous work on magneto-plasmonic hetero-nanostructures including: (i) their synthesis from simple “one-step” to complex “multi-step” routes, including seed-mediated and non-seed-mediated methods; and (ii) the characterization of their multifunctional features, with a special emphasis on the relationships between their synthesis conditions, their structures and their properties. It also focuses on the most important progress made with regard to their use in nanomedicine, keeping in mind the same aim, the correlation between their morphology—namely spherical and non-spherical, core-satellite and core-shell, and the desired applications.

“…There has been an increasing research interest in magnetoplasmonic effects to improve SPR sensitivity (Sepúlveda et al 2006, Regatos et al 2010, Manera et al 2011, Chou et al 2014, Caballero et al 2016, Ignatyeva et al 2016, Grunin et al 2016, Maccaferri et al 2015. This mechanism was proposed by Sepúlveda et al (2006), where magneto-optical (MO) activity was combined with SPRs for decreasing the limit of detection of a Kretschmann-like SPR platform.…”

The strong enhancement and localization of electromagnetic field in plasmonic systems have found applications in many areas, which include sensing and biosensing. In this paper, an overview will be provided of the use of plasmonic phenomena in sensors and biosensors with emphasis on two main topics. The first is related to possible ways to enhance the performance of sensors and biosensors based on surface plasmon resonance (SPR), where examples are given of functionalized magnetic nanoparticles, magnetoplasmonic effects and use of metamaterials for SPR sensing. The other topic is focused on surface-enhanced Raman scattering (SERS) for sensing, for which uniform, flexible, and reproducible SERS substrates have been produced. With such recent developments, there is the prospect of improving sensitivity and lowering the limit of detection in order to overcome the limitations inherent in ultrasensitive detection of chemical and biological analytes, especially at single molecule levels.
