Magnetoplasmonic Nanosensors

Magnetoplasmonic nanocomposites (MPNCs) manufactured by combining MNPs with PNPs combine advantages of magnetic and plasmonic NPs such as high biocompatibility and chemical stability, ease of synthesis, and modification, wide-range spectral optical properties between others. The methods such as chemical reduction, thermal decomposition, solvothermal method, microemulsion method, etc. for the synthesis of these structures in the form of a heterodimer, multicomponent-doped hybrid, spherical, or nonspherical core–shell or core–satellite have been with interested for biosensing applications. The optical and magnetically properties of MNPs can be tunable by the change of morphology, composition, and size of MPNCs to suit the desired final applications. In this chapter, we discuss the various synthesis procedures and the main sensing applications of MPNCs.
