    Master-uppsats, KTH/Tillämpad fysik

    Författare :Ronak Kakadiya; [2022]
    Nyckelord :Nanoparticles; Nanoclusters; SPIONs; Microwave-assisted synthesis; Solvothermal; Core-Shell; Bioconjugation; Green Chemistry.; Nanopartiklar; Nanokluster; SPIONs; Mikrovågsassisterad syntes; Solvotermisk; Core-Shell; Biokonjugation; Grön kemi.;

    Sammanfattning : Nanoparticles (NPs) have been part of our daily lives whether we are aware of it ornot and are continuously shaping our world of tomorrow. They are employed in awide range of applications such as in sunscreens, breaking down microplastics inthe ocean and scaling down beyond Moore’s law. LÄS MER

  3. 2. Circle-to-circle amplification to improve the sensitivity of a magnetic nanoparticle-based DNA detection protocol

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekylärbiologi

    Författare :Anna Nilsson; [2021]
    Nyckelord :circle-to-circle amplification; rolling circle amplification; nanotechnology; DNA detection; magnetic nanoparticles;

    Sammanfattning : Magnetic nanoparticles have great potential in the biomedical and diagnostics field. Due to their small size, the particles have a high surface-to-volume ratio which enables for biofunctionalisation with different molecular probes. This makes itpossible to target them against a wide variety of biomarkers. LÄS MER

  4. 3. Characterization of Magneto-Dielectric Materials for Microwave Devices

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Joseph Lazraq Byström; [2020]
    Nyckelord :magneto-dielectric materials; permittivity; permeability; losses; antenna and filter miniaturization;

    Sammanfattning : There is an increasing interest in using new composite materials in microwave devices, to reduce size and weight while maintaining similar performances. A new promising material group is named magneto-dielectric materials, which have the permittivity and permeability values both larger than one. LÄS MER

  5. 4. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Markus Back; [2020]
    Nyckelord :Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Sammanfattning : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. LÄS MER

  7. 5. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Nyckelord :Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Sammanfattning : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. LÄS MER
