  1. 1. Differential Magnetic Biosensor using HTS SQUID Gradiometer

    Författare :Sobhan Sepehri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; magnetic bioassay; diagnostics; RCA; microfluidics; magnetic nanoparticle; point-of-care; rolling circle amplification; differential ac susceptibility; biosensor;

    Sammanfattning : A fundamental tool for containing an epidemic outbreak and mitigating its effects is early diagnostics. Currently, most of the diagnostic tests are performed by trained staff in centralized labs, which are expensive and time-consuming to establish and operate. Lack of access to such facilities could have devastating effects. LÄS MER

  3. 2. Biomolecular Recognition Based on Field Induced Magnetic Bead Dynamics

    Författare :Rebecca Stjernberg Bejhed; Peter Svedlindh; Klas Gunnarsson; Maria Strömme; Teresa Zardán Gómez de la Torre; Christer Johansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Magnetic biosensor; magnetic nanoparticle; DNA detection; Teknisk fysik; Engineering Science;

    Sammanfattning : In this thesis, three different read-out techniques for biomolecular recognition have been studied. All three techniques rely on the change in dynamic behaviour of probe functionalised magnetic beads after binding to a biomolecular target complementary to the probe. LÄS MER

  4. 3. Strategies for developing peptide and protein selective plastic antibodies

    Författare :Rashmi Mahajan; Ian A. Nicholls; Subramanian Suriyanarayanan; Börje Sellergren; Alessandra Maria Bossi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Competitive assays; molecularly imprinted polymer; magnetic nanoparticle; nanogel; nanoparticle; plastic antibody; solid-phase synthesis; QCM.; Biokemi; Biochemistry;

    Sammanfattning : The objective of the thesis was to explore approaches for the development of molecularly imprinted materials with predetermined selectivity for peptide or protein targets. In particular, the work has focused on molecularly imprinted nanoparticles synthesized using solid-phase synthesis protocols. LÄS MER

  5. 4. Magnetic Nanoparticle Based Biosensors for Pathogen Detection and Cancer Diagnostics

    Författare :Bo Tian; Mattias Strömberg; Peter Svedlindh; Hakho Lee; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic biosensors; magnetic nanoparticles; homogeneous assays; volumetric sensing; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : This thesis describes several magnetic nanoparticle (MNP)-based biosensing strategies which take advantage of different magnetic sensors, molecular tools and nanotechnologies. Proposed biosensors can be classified into three groups, i.e., immunoassay-based, molecular amplification-based, and nanoparticle assembly-based. LÄS MER

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

    Författare :Erik Wetterskog; Lennart Bergström; Markus Niederberger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron oxide; nanoparticle; synthesis; self-assembly; characterization; electron microscopy; scattering; magnetic properties; Materials Chemistry; materialkemi;

    Sammanfattning : 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.
