Magnetic resonance imaging contrast agents for chemical sensing
Magnetic resonance imaging (MRI) is frequently used for examining the human body. MRI contrast agents currently used in the clinic assist physicians in locating problematic areas, but other tools are needed to interrogate the chemical environment of these areas once found. The fast clearance rate …

Gadolinium Endohedral Metallofullerenes for Future Magnetic Resonance Imaging Contrast Agents
… shown the potential to become next generation magnetic resonance imaging (MRI) contrast agents due to their significantly improved efficiency and safety, as well as multi-day body retention which allows for a longer surgery and observation compared to current contrast agents. In Chapter 1, I …

The Use of Ultrasound-Targeted Microbubble Destruction in Mediated Delivery of a Gadolinium Magnetic Resonance Imaging Contrast Agent Into Fibroblast Cells In Vitro
A method for delivering Gd-based MRI contrast agents by ultrasound-targeted microbubble destruction into fibroblast cells in vitro is presented. First, MRI contrast agents Gd-F-DOTP-ME and Gd-DOTA-4iBA are shown to associate with liposome microbubbles used as ultrasound contrast agents. Repeated …

Magnetic resonance investigations of pH in microemulsions
… this thesis has investigated the development of magnetic resonance (MR) techniques to probe the pH in aqueous solutions and reverse micelles formed in CTAB, Triton-X and AOT microemulsions. These techniques have enabled visualisation of propagating acidity fronts in the bromate-sulfite reaction …

Design, Synthesis, and Characterization of Magnetite Clusters using a Multi Inlet Vortex Mixer
Superparamagnetic nanoparticles have potential applications in targeted drug delivery and as magnetic resonance imaging contrast agents. Magnetite clusters are of particular interest for these applications because they provide higher magnetic flux (under a magnetic field) than individual magnetite …

Shape dependent iron oxide nanoparticles for simultaneous imaging and therapy
… of shape dependent iron oxide nanoparticles as magnetic resonance imaging contrast agents. In addition to biocompatibility, nanoparticles provide a foundation for implementing imaging guided drug delivery systems. We begin with the synthesis of iron oxide nanoparticles of varying sizes and …

Synthesis and characterization of silicon nanowires, silicon nanorods, and magnetic nanocrystals
Silicon nanowires, silicon nanorods, and magnetic nanocrystals have shown interesting size, shape, mechanical, electronic, and/or magnetic properties and many have proposed their use in exciting applications. However, before these materials can be applied, it is critical to fully understand their …

The Preparation, Functionalization and Biomedical Applications of Carbonaceous Nanomaterials
… weight of the PEG from 350 to 5000. The 1H magnetic resonance relaxivities of the materials were studied at 0.35 T, 2.4 T and 9.4 T. Their relaxivities were found to increase as the molecular weight of the PEG decreased, which is attributed to the increasing aggregate size. The aggregate …
