“…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 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.

An undeniable advantage of magnetorheological supports is adaptability of their stiffness properties and their real-time adjustability. Thus, it is important to research the issues of improving magnetorheological damping systems and developing simulation and calculation methods. It is noteworthy that magnetorheological systems have instable operating parameters due to heating of the magnetorheological environment in electromagnetic control fields, and change in viscosity properties of the carrier fluid. There are various ways to solve this operational problem. To avoid this negative factor, the magnetorheological environment requires an optimal thermostating. To stabilize the temperature parameters, the thermostating system should be dynamically controlled, and new constructive solutions should be implemented. The presented thermostating system has an original patented construction of a rheological thermostatic throttle with thermoelectric elements that greatly improves cooling of the working environment, and makes it possible to faster and accurately obtain the desired operating temperatures. The paper presents a methodology for calculating the stiffness properties of a magnetorheological fluid chamber that includes sub chambers with individual control electromagnets and variable dissipative-stiffness properties. We considered the ways for optimizing the distribution of dissipative-stiffness properties of subchambers, and their rational combination to develop the most advanced damping fluid systems. The described magnetorheological damping system has an original patented magnetodynamic pump that uses helical electromagnetic fields to transport the magnetorheological fluid.

“…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.
