“…[63] The FePt nanoparticles have also been used as seeds to synthesize FePt-Ag nanoparticles. [64] These bimodal nanoparticles, along with several other bimodal structures reported recently, [65][66][67] have two closely connected functional units, and may exhibit novel magnetic and optical properties that can be tuned by controlling the interface interactions between the two units.

This paper reviews recent advances in chemical synthesis, self‐assembly, and potential applications of monodisperse binary FePt nanoparticles. After a brief introduction to nanomagnetism and conventional processes of fabricating FePt nanoparticles, the paper focuses on recent developments in solution‐phase syntheses of monodisperse FePt nanoparticles and their self‐assembly into nanoparticle superlattices. The paper further outlines the surface, structural, and magnetic properties of the FePt nanoparticles and gives examples of three potential applications in data storage, permanent magnetic nanocomposites, and biomedicine.

“…Such shapes constitute a virtual zoo of "nano-animals" including aptly named nanoacorns, nano-centipedes, nano-guitars, nanosquids, nanovials and nanowhiskers. [2][3][4][5][6] In contrast, the comparable list of colloidal particle compositions and shapes is significantly more limited. Self-assembly requires particles with narrow distributions in size and shape.…”

“…Co 9 S 8 -PdS x hetero-dimer MHNCs with acorn profile (Figures 5A,B) were produced by co-pyrolysis of the corresponding cobalt and copper carboxylate precursors in the presence of alkylthiols as the sulfur source (Teranishi et al, 2004(Teranishi et al, , 2007a. As these metal sulfides are only partially miscible and feature large interfacial energy, a solid-solution could not be created, whereas phase segregation of two materials took place instead.…”

Colloidal Magnetic Heterostructured Nanocrystals with Asymmetric Topologies: Seeded-Growth Synthetic Routes and Formation Mechanisms

Colloidal inorganic nanocrystals (NCs), free-standing crystalline nanostructures generated and processed in solution phase, represent an important class of advanced nanoscale materials owing to the flexibility with which their physical-chemical properties can be controlled through synthetic tailoring of their compositional, structural, and geometric features and the versatility with which they can be integrated in technological fields as diverse as optoelectronics, energy storage/conversion/production, catalysis, and biomedicine. In recent years, building upon mechanistic knowledge acquired on the thermodynamic and kinetic processes that underlie NC evolution in liquid media, synthetic nanochemistry research has made impressive advances, opening new possibilities for the design, creation, and mastering of increasingly complex "colloidal molecules," in which NC modules of different materials are clustered together via solid-state bonding interfaces into free-standing, easily processable multifunctional nanocomposite systems. This review will provide a glimpse into this fast-growing research field by illustrating progress achieved in the wet-chemical development of last-generation breeds of allinorganic heterostructured nanocrystals (HNCs) in asymmetric non-onionlike geometries, inorganic analogues of polyfunctional organic molecules, in which distinct nanoscale crystalline modules are interconnected in heterodimer, hetero-oligomer, and anisotropic multidomain architectures via epitaxial heterointerfaces of limited extension. The focus will be on modular HNCs entailing at least one magnetic material component combined with semiconductors and/or metals, which hold potential for generating enhanced or unconventional magnetic behavior, while offering diversified or even new chemical-physical properties and functional capabilities. The available toolkit of synthetic strategies, all based on the manipulation of seeded-growth techniques, will be described, revisited, and critically interpreted within the framework of the currently understood mechanisms of colloidal heteroepitaxy.
