This book offers a detailed discussion of the complex magnetic behavior of magnetic nanosystems, with its myriad of geometries (e.g. core-shell, heterodimer and dumbbell) and its different applications. It provides a broad overview of the numerous current studies concerned with magnetic nanoparticles, presenting key examples and an in-depth examination of the cutting-edge developments in this field. This contributed volume shares the latest developments in nanomagnetism with a wide audience: from upper undergraduate and graduate students to advanced specialists in both academia and industry. The first three chapters serve as a primer to the more advanced content found later in the book, making it an ideal introductory text for researchers starting in this field. It provides a forum for the critical evaluation of many aspects of complex nanomagnetism that are at the forefront of nanoscience today. It also presents highlights from the extensive literature on the topic, including the latest research in this field.
This book presents in a concise way the Mie theory and its current applications. It begins with an overview of current theories, computational methods, experimental techniques, and applications of optics of small particles. There is also some biographic information on Gustav Mie, who published his famous paper on the colour of Gold colloids in 1908. The Mie solution for the light scattering of small spherical particles set the basis for more advanced scattering theories and today there are many methods to calculate light scattering and absorption for practically any shape and composition of particles. The optics of small particles is of interest in industrial, atmospheric, astronomic and other research. The book covers the latest developments in divers fields in scattering theory such as plasmon resonance, multiple scattering and optical force.

Nanoparticles for Biomedical Applications: Fundamental Concepts, Biological Interactions and Clinical Applications brings into one place information on the design and biomedical applications of different classes of nanoparticles. While aspects are dealt with in individual journal articles, there is not one source that covers this area comprehensively. This book fills this gap in the literature. Outlines an in-depth review of biomedical applications of a variety of nanoparticle classes Discusses the major techniques for designing nanoparticles for use in biomedicine Explores safety and regulatory aspects for the use of nanoparticles in biomedicine
It cannot be overstated that nanoparticles have earned their reputation for being famously practical, from simple artisan pottery to biomedical applications. Since Faraday's famous observations into thin gold films during the 1800's, nanoparticle research has shown the world that experimentation into synthesizing nanoparticles, and more interestingly core/shell nanoparticles, will prove worthwhile in the fight against cancerous cells. As it stands, carbon-coated iron-based core/shell nanoparticles have shown promising results, thrice in high magnetic saturation, high coercivity, and biocompatibility. The objective of this thesis is to compare already synthesized iron-based core/shell nanoparticles to our synthesized nanoparticles, as well as indicate another potential precursor candidate to be used for synthesis of nanoparticles. The magnetic properties of the product of pyrolysis of iron phthalocyanine annealed under an oxygen-rich environment at different temperatures are investigated with a vibrating sample magnetometer (VSM), scanning electron microscope (SEM), and X-ray diffractometry (XRD). The magnetic hysteresis curve of different samples measured at 10 K and 300 K illustrates the strong magnetic responses to a varying magnetic field under a VSM. The magnetic saturation (MS), magnetic remanence (MR) and coercivity (HC) values for all samples are listed in Tables 3 through 6. We investigate the effects of annealing at different temperatures in an oxygen-rich environment for iron phthalocyanine, and demonstrate that as the annealing temperature is elevated, HC increases while the MS decreases. As the annealing temperature is elevated further above an optimal value, a sharp decreasing change of magnetic parameters can be related to the degradation of iron and the formation of iron oxide particles in different phases such as magnetite (Fe3O4), maghemite (Îđ-Fe2O3), and hematite (Îł-Fe2O3). To conclude, the magnetic properties of iron phthalocyanine post pyrolysis can be varied as a function of annealing temperature as shown in Figure 32 and 33. More detailed studies will be necessary to define nanoparticle distribution, their morphology, sizes, and crystal structure, along with the percent composition of inspected samples. The magnetic properties of the product of pyrolysis of iron porphyrin were also studied for comparison and their magnetic properties can be seen in Table 7. While more research into higher annealed temperatures should be performed, iron porphyrin has shown to be a promising candidate for synthesis of nanoparticles due to its interesting features, mainly its constant MR/MS ratio over different annealed temperatures.
