“…Magnetic-plasmonic heterodimers can be obtained by chemical synthesis (e.g., polyol method for Ag-FeCo hybrid NPs) [47], and can be composed of metallic-metallic or metallic-nonmetallic materials, such as Fe-Au heterodimers or Fe 3 O 4 -Au heterodimers, respectively. Due to the higher stability in biological media and the predominant hydrophilicity, metallic-nonmetallic hybrid MNPs are particularly interesting as host nanoparticles, and due to the potential applications, they urge as highly promising nanotheranostic agents [48].…”

Technological development is in constant progress in the oncological field. The search for new concepts and strategies for improving cancer diagnosis, treatment and outcomes constitutes a necessary and continuous process, aiming at more specificity, efficiency, safety and better quality of life of the patients throughout the treatment. Nanotechnology embraces these purposes, offering a wide armamentarium of nanosized systems with the potential to incorporate both diagnosis and therapeutic features, towards real-time monitoring of cancer treatment. Within the nanotechnology field, magnetic nanosystems stand out as complex and promising nanoparticles with magnetic properties, that enable the use of these constructs for magnetic resonance imaging and thermal therapy purposes. Additionally, magnetic nanoparticles can be tailored for increased specificity and reduced toxicity, and functionalized with contrast, targeting and therapeutic agents, revealing great potential as multifunctional nanoplatforms for application in cancer theranostics. This review aims at providing a comprehensive description of the current designs, characterization techniques, synthesis methods, and the role of magnetic nanoparticles as promising nanotheranostic agents. A critical appraisal of the impact, potentialities and challenges associated with each technology is also presented.

“…The most desired morphologies of the iron–gold NPs include core–shell, dumbbell-shaped, Janus-shaped, flower-shaped, star-shaped, octahedral-shaped, and rod-shaped, as depicted in Figure 2 . The synthesis of these morphologies, shape, and final performance depends on their junctional mode and interfacial morphology of the heterodimer structures [ 74 ].…”

“…Studies on the dumbbell heterodimers have demonstrated that the symmetry and free surface areas of dumbbell heterodimers are greater than those of randomly decorated ones, making them desirable for use in photo- and bio-catalysis applications [ 87 ]. The synthesis of the iron–gold heterodimers by the seed-mediated technique of non-spherical magnetic particles can affect their plasmonic properties during the interfacial morphology [ 74 ].…”

Recently, there has been an increased interest in iron–gold-based hybrid nanostructures, due to their combined outstanding optical and magnetic properties resulting from the usage of two separate metals. The synthesis of these nanoparticles involves thermal decomposition and modification of their surfaces using a variety of different methods, which are discussed in this review. In addition, different forms such as core–shell, dumbbell, flower, octahedral, star, rod, and Janus-shaped hybrids are discussed, and their unique properties are highlighted. Studies on combining optical response in the near-infrared window and magnetic properties of iron–gold-based hybrid nanoparticles as multifunctional nanoprobes for drug delivery, magnetic–photothermal heating as well as contrast agents during magnetic and optical imaging and magnetically-assisted optical biosensing to detect traces of targeted analytes inside the body has been reviewed.

Binary, ternary, and other high-order plasmonic heteromers possess remarkable physical and chemical properties, enabling them to be used in numerous applications. The seed-mediated approach is one of the most promising and versatile routes to produce plasmonic heteromers. Selective growth of one or multiple domains on desired sites of noble metal, semiconductor, or magnetic seeds would form desired heteromeric nanostructures with multiple functionalities and synergistic effects. In this work, the challenges for the synthetic approaches are discussed with respect to tuning the thermodynamics, as well as the kinetic properties (e.g., pH, temperature, injection rate, among others). Then, plasmonic heteromers with their structure advantages displaying unique activities compared to other hybrid nanostructures (e.g., core-shell, alloy) are highlighted. Some of the main most recent applications of plasmonic heteromers are also presented. Finally, perspectives for further exploitation of plasmonic heteromers are demonstrated. The goal of this work is to provide the current know-how on the synthesis routes of plasmonic heteromers in a summarized manner, so as to achieve a better understanding of the resulting properties and to gain an improved control of their performances and extend their breadth of applications.
