- Аннотация: In recent years the developments in the magnetic nanoparticle synthesis methods have given wide possibilities for investigation and exploiting their unique properties. The assembly of nanoparticles and formation of organized nanoparticulate nanostructures has shown the potential of numerous applications. Magnetic nanoparticles can be assembled in different dimensions and arrays using a variety of techniques as described in this Chapter. Those techniques are usually nonspecific for magnetic nanoparticles (excepting specific magnetic interactions) and can be used for building-up of nanoparticulate structures of various nature. Future efforts will be directed to the building-up of highly-ordered defect-free and reproducible nanoparticles assemblies and nanostructures what is necessary for development of reliable devices. Different methods of nanoparticle assembly offer different advantages and disadvantages. Relatively simple methods based on evaporation-induced assembly can produce large structures but there is a little scope for controlling the interparticle distances or structure of assemblies. Assembly methods based on chemical bonding and conjugations allow tailoring surface properties of the nanoparticles, however, this generally involves careful and complicated tailoring of ligand composition and surface functionalities on nanoparticles, substrates or template surfaces making those methods more complicated and chemically sophisticated. Future perspectives in developments of nanoparticulate structures are connected also with creating of complex, multicomponent, hybrid, integrated and, as a result with, multifunctional nanomaterials and nanosystems. The resulting properties of such nanosystems are substantially dependent on the nano-scale organization of structural and functional nano-components and their collective behavior. It opens possibilities for fine tuning and controlling the properties of integrated nanosystems what is important for applications. To realize those possibilities the insights into basic mechanisms, which govern the nanoscale processes of inorganic phase growth and morphological evolution, interparticle interactions and structural organization of nanoparticulate systems and nanostructures are necessary. The investigation of those mechanisms and development of novel organized functional and polufunctional nanomaterials will be the subject of future research. The described synthetic strategies and methods can be useful for investigation of fundamental mechanisms of nano-scale structure formation, organization and transformations in complex nanosystems. The methods are relatively simple, rapid, inexpensive and allow large-scale preparation of organized nanostructures at ambient and ecologically-friendly conditions. It makes them promising practical instruments for molecular nanotechnology with potential for nanobiotechnological and biomedical applications.
