  1. 6. Methods to study device induced aggregation of proteins

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Marie Therese von Wowern; [2023]
    Nyckelord :protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. LÄS MER

  3. 7. Investigation on Liquid-Liquid Phase Separation in Immunoglobulin G Solutions

    Kandidat-uppsats, Stockholms universitet/Fysikum

    Författare :Lovisa Jansson; [2023]
    Nyckelord :Protein; Liquid-Liquid Phase Separation; Microscopy; Light Scattering;

    Sammanfattning : Liquid-liquid phase separation (LLPS) is an important phenomenon in soft condensed matter that explains many properties of membraneless organelles in living cells. The research on this topic is, therefore, a field with a wide range of applications such as biopharmacy and biomaterials. LÄS MER

  4. 8. En utvärdering av ett nytt test av morfologisk medvetenhet för elever i årskurs 4

    Magister-uppsats, Umeå universitet/Logopedi

    Författare :Johanna Johansson; Annie Stattin; [2023]
    Nyckelord :Morfologi; Logopedi; Morfologisk testning;

    Sammanfattning : Bakgrund. Morfologisk medvetenhet definieras som förmågan att kunna förstå och analysera ords inre struktur samt hur ord böjs och bildas. Morfologisk medvetenhet tillhör tillsammans med andra byggstenar vår språkliga medvetenhet och är viktig för utveckling av litteracitet. LÄS MER

  5. 9. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Owais Khalil; [2023]
    Nyckelord :Sponge phase; lipid nanoparticles; microfluidics; SAXS; cryo-TEM; DLS; chemical engineering; Chemistry;

    Sammanfattning : Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. LÄS MER

  7. 10. Emulsifying properties of cellulose oxalate and pectin from Norway spruce bark

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Semonti Hussain; [2022]
    Nyckelord :Cellulose oxalate COX ; Bark; Norway spruce; Pectin; Pickering emulsion; Pulp;

    Sammanfattning : Nanocellulose is a sustainable material and has shown interesting properties in various applications. One such application is Pickering emulsion, where the nanocellulose stabilizes the oil and water interface. LÄS MER
