Syntheses, Properties, and Potential Applications of Multicomponent magnetic Nanoparticles Adv. Funct. Mater. 2008, 18, 391–400 Dr.Sun应该算是这方向的牛人 Professor Sun's research in nanomaterials involves two related areas: (1) chemical synthesis and self-assembly of nanoparticles; (2) construction and elaboration of functional nanoparticles and their assemblies for applications in biomedicine, catalysis, information storage and composite nanostructures.  Synthe  sis and Self-AssemblyWe utilize the so called "bottom-up" approach for the synthesis of monodisperse nanoparticles. Recent focus has been on the synthesis of magnetic nanoparticles of Co, MFe2O4 and FePt by reduction of metal salts and/or thermal decomposition of organometallic precursors. The size, composition, and shape of these nanoparticles can be tuned by controlling reaction parameters, such as the reactant ratio and concentrations, temperature, and time. We are also exploring other synthetic approaches to prepare multi-component and multi-functional nanoparticles of the alloy-type (e.g. CoFe), core/shell type (e.g. CoFe/Fe3O4), and dumbbell-like (e.g. Au-Fe3O4) materials. Through proper surface modification, these nanoparticles can be dispersed in various media, or they can self-assemble into superlattice structures. The effects of particle size, shape, composition, and interparticle spacing on physical and chemical properties of the nanostructures constitute issues of the critical importance that are addressed by our research. Magnetic Nanoparticles for Biomedical Applications Recent advances in the synthetic control of nanoparticle monodispersity suggest that the fabrication of nanoparticle-based bio-probes with ultra-high sensitivity and efficacy should be possible. We are working to make a series of biocompatible multifunctional magnetic nanoparticles, and subsequently establish their bio-recognition and delivery capabilities. Through collaborations with other researchers, we plan to integrate these multifuctional nanoparticles into bio-systems for potential highly efficient diagnostic and therapeutic applications. Nanoparticles for Catalytic Applications The rapid progress in the construction of nanoparticles with controllable size, shape, and electronic properties has made it possible to rationally design and synthesize nanoparticle-based catalysts. Our goals are to prepare transition metal based nanoparticles with controlled size, composition, and shape and to study their self-assembled structures for catalytic applications in nanotube/nanowire formation and fuel-cell reactions. Magnetic Nanoparticle Assembly for Information Storage Applications As a magnet in nanometer scale, a magnetic nanoparticle can be used to support magnetization transition for information storage applications. The ultimate media goal is that each nanomagnet can support one bit of the digital information. We have been exploring the chemical synthesis and self assembly to fabricate 2-dimensional magnetic nanoparticle arrays, and will use the shape of the particles to control the magnetization direction of the self-assembled nanoparticle array for ultrahigh density information storage applications. Composite Nanostructures via Nanoparticle Self-Assembly Nanocomposites refer to engineered materials consisting of at least one nanoscale constituent. By independently tuning the size and composition of each component, followed by engineering the assembly, the nanostructures can be tailored for physical and chemcial properties that do not exist in the single component nanomaterials. The self-assembly approach is being used to prepare multi-component systems to provide both a model for studying fundamental relationships between nanostructure and inter-particle interactions, and to provide a practical route to novel functional nanodevices. |
