  1. 1. Karakterisering av nanopartikelgenerator för lungdiagnostik med AiDA-metoden

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Erik Chen; Adam Lüning; [2022]
    Nyckelord :Aerosol; nanopartiklar; nanopartikelgenerator; AiDA; Technology and Engineering;

    Sammanfattning : Lung diseases such as chronic obstructive pulmonary disease (COPD) is one of the most common casue of death worldwide, yet the lungs are one of the most difficult parts of the body to examine. Today's technology hinder the diagnosis of the lungs and great difficulties occurs when trying to find the cause of illness. LÄS MER

  3. 2. Optimizing the Production of Aurora Kinase A and Validation of Constructs with different Sequential Lengths

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Linnea Pierre; [2022]
    Nyckelord :Protein; Protein chemistry; Aurora Kinase A; Aurora A; Cancer; Structural Biology; Cancer research;

    Sammanfattning : Aurora Kinase A is a kinase involved in multiple signaling pathways and interactions during mitosis, making it an essential kinase that deregulated causes cancer diseases in affected patients. Structural research shows mainly static snapshots of possible conformations of the partly disordered protein. LÄS MER

  4. 3. Separation of Nanoporous Silica Particles

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

    Författare :Frida Preuss; Julia Asp; Sofia Larsson; Stephanie Kylington; [2020]
    Nyckelord :Monodispersity; particle size distribution; density gradient; centrifugation; silica;

    Sammanfattning : In this study a sample of particles in a size region of 0.05-10 μm were run through a centrifugation process with the ambition to make it monodisperse. The product requirements were stated as follows, particles within the size range of 2 to 3.8 μm should be isolated and separated from the sample with a D90/D10 < 1. LÄS MER

  5. 4. Towards monodisperse Silicon Nanocrystals: density gradient centrifugation applied on commercial gold nanoparticles

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Faraz Khavari; [2016]
    Nyckelord :Silicon Nanocrystals; density gradient centrifugation; gold nanoparticles;

    Sammanfattning : The application of silicon nanocrystals as non-toxic bio-labels and downconverters requires their uniform size distribution in order to minimize the inhomogeneous broadening of the photoluminescence peak. In this thesis, we set the basis for their size-separation via the density-gradient centrifugation method. LÄS MER

  7. 5. Investigation on Stability of Cesium Lead Bromide quantum dots

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Lina Le; [2016]
    Nyckelord :kemisk fysik; chemical physics; Chemistry;

    Sammanfattning : Monodisperse colloidal quantum dots of fully inorganic cesium lead bromide CsPbBr3 are synthesised at two distinguished temperatures (120 and 180oC) using inexpensive commercial precursors. The stability of these quantum dots is studied under three different conditions by measuring absorption as well as photoluminescence as functions of time. LÄS MER
