Book Description
Suspensions of both dispersed and clustered iron oxide nanoparticles are of interest for biomedical applications as diagnostic and therapeutic agents due to their bio-compatibility and interesting magnetic and magnetic resonance properties. Their application is critically dependent on the fact that these properties are highly size-dependant. By developing NP synthesis and assembly methods, to provide improved size control at the two levels of organisation, NP suspensions with controlled emergent magnetic properties have been prepared. The first part of this thesis presents the size-controlled synthesis of magnetic nanoparticles whose surface is functionalised with a wide range of stabilising ligands. An investigation was undertaken to elucidate the effect of the stabilising ligands on the physical properties. The second part of the thesis presents a novel method for the reproducible assembly, in suspension, of NPs to form clusters. The method can be used to produce clusters of controlled size in large quantities; it is also shown that the kinetics of assembly can be easily controlled and that this influences the emergent magnetic properties. Arising from this observation a study was undertaken to determine the role of cluster architecture on the magnetic resonance properties of their aqueous suspensions.

Book Description
Magnetic nanocomposites and nanoparticle assemblies have gained significant interest for biomedical applications including MRI, hyperthermia and targeted drug delivery. Their efficacy depends on colloidal stability, optimal magnetic properties and appropriate size and surface chemistry for good biodistribution. The first part of this thesis focuses on the preparation of sub 20 nm magnetic nanoparticles (IONP) and the modification of their surface charge for subsequent encapsulation or adsorption to the polymer poly n-butyl cyanoacrylate (PACA) to produce IONP dilute assemblies. In addition to this, IONP-dense assemblies were prepared using established methods, and the effect of IONP density on the magnetic resonance properties of the assemblies was assessed. It was found that the NMR response was very sensitive to the IONP density and also to the structure of the assembly. This suggests potential routes to novel materials with tunable MRI properties. The second part of the thesis focuses on the assembly of IONP into dense assemblies (or clusters) in organic media using a novel in situ assembly technique based on reducing surfactant coverage. Particular attention was paid to the kinetics of the assembly process and the effect of adding surfactants and/or gold nanoparticles to the metastable IONP assemblies was also studied.

Book Description
Magnetic nanoparticles with diameters in the range of a few nanometers are today at the cutting edge of modern technology and innovation because of their use in numerous applications ranging from engineering to biomedicine. A great deal of scientific interest has been focused on the functionalization of magnetic nanoparticle assemblies. The understanding of interparticle interactions is necessary to clarify the physics of these assemblies and their use in the development of high-performance magnetic materials. This book reviews prominent research studies on the static and dynamic magnetic properties of nanoparticle assemblies, gathering together experimental and computational techniques in an effort to reveal their optimized magnetic properties for biomedical use and as ultra-high magnetic recording media.

Book Description
Superparamagnetic iron oxide nanoparticles are of great interest in the field of biomedicine at present due to their highly tuneable magnetic properties, which can be modulated by the application of an external magnetic field. Controlled assembly of these nanoparticles to form functional clusters allows for the improved and nuclear magnetic response, while retaining advantageous superparamagnetic character. In the first half of this thesis a novel approach for the controlled assembly of nanoparticles by a polymer mediated approach to form superparamagnetic clusters is introduced. Process optimization and the effects of assembly on the magnetic and magnetic resonance response are investigated. In the second half, nanoparticle morphology is addressed; in particular the production of cubic nanoparticles and the assembly of these into functional clusters with higher inherent magnetocrystalline anisotropy is described.
