  1. 1. Building crystals out of crystals Synthesis, structure and magnetic properties of iron oxide nanoparticles and self-assembled mesocrystals

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Erik Wetterskog; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron oxide; nanoparticle; synthesis; self-assembly; characterization; electron microscopy; scattering; magnetic properties; materialkemi; Materials Chemistry;

    Abstract : This thesis is focused on the fabrication and characterization of self-assembled arrays of magnetic iron oxide (Fe3O4, γ-Fe2O3 and Fe1-xO) nanoparticles. The synthesis of spherical and cubic iron oxide nanocrystals, with sizes between 5 and 30 nm and narrow size distributions, is demonstrated, along with a rigorous morphological characterization of the cubic nanoparticles.

  2. 2. In vitro characterization of nanodrugs at model lipid membranes

    University dissertation from Chalmers University of Technology

    Author : Rickard Frost; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofysik; Biophysics; nanomedicine; drug delivery; nanoparticle; drug carrier; supported lipid bilayer; cell membrane; QCM-D; in vitro screening;

    Abstract : The use of nano-sized drug carriers to improve the efficiency of drug delivery has become well established during the past decades. New nanoparticle (NP) formulations for the administration of biopharmaceuticals (e.g. proteins and peptides) emerge at an increasing rate and the need for methods to evaluate their properties is expanding.

  3. 3. De Novo Design and Characterization of Surface Binding Peptides - Steps toward Functional Surfaces

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Patrik Nygren; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; design; nanoparticle; CD; Amino acid; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : The ability to create surfaces with well-defined chemical properties is a major research field. One possibility to do this is to design peptides that bind with a specific secondary structure to silica nanoparticles. READ MORE

  4. 4. Metal Oxide Nanoparticles for Contrast Enhancement in Magnetic Resonance Imaging Synthesis, Functionalization and Characterization

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Maria Ahrén; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis work focuses on the design and production of nanoparticle based contrast agents for signal enhancement in magnetic resonance imaging (MRI). Three different synthesis routes are explored, primarily to produce crystalline gadolinium oxide (Gd2O3) nanoparticles, and surface modification is done to obtain stable, dispersible, biocompatible probes inducing high proton relaxivities.

  5. 5. Ceria Nanoparticle Hybrid Materials Interfacial Design and Structure Control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Eric Johansson Salazar-Sandoval; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This doctoral thesis addresses the challenge of bringing two very different materials into intimate chemical contact: inorganic metal oxide nanoparticles and acrylic polymers. In order to achieve this ambitious goal, the work has been divided into a series of more accessible tasks. READ MORE
