1. 1. Study of surfactant-preservative and protein-preservative interactions in multi-dose injectable formulation

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Javier Lagares Martín; [2023]
   Keywords : Phenol; polysorbate 80; cloud point; somatropin; aggregation; titration; light scattering; salt; surfactant; preservative; protein; tonicity adjusting agents; multi-dose injectable formulation; pharmaceutical technology; Technology and Engineering;

   Abstract : Multidose injectable formulations require a preservative such as phenol to ensure sterility and protection against microbial contamination during clinical use. However, it is known that the interaction between these components and non-ionic surfactants such as polysorbate 80, also found in this type of formulations, present incompatibilities, which can lead to decreases in the efficacy of the product.

3. 2. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

   University essay from Lunds universitet/Kemiteknik (CI)

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

   Abstract : 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. READ MORE

4. 3. Laser Scattering for Fast Characterization of Cellulose Filaments

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
   Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

   Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

5. 4. Green Coacervates for Pharma and Food

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Izabella Imets; Andreas Vallin; [2022]
   Keywords : MSc; coacervate; biosurfactant; biopolymer; SAXS; DLS; elliposometry; pharmaceutical technology; Technology and Engineering;

   Abstract : Anionic biosurfactant-cationic biopolymer systems were investigated to identify and characterize a coacervation window. The characterization of the systems was performed with dynamic light scattering, small angle x-ray scattering and in-situ ellipsometry. READ MORE

6. 5. Development and characterization of an eco-friendly cosmeceutical formulation with optimal performance.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)
