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

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

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

   Abstract : 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. READ MORE

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. Solubility of Wood Xylans, Effect of pH and Concentration

   University essay from KTH/Glykovetenskap

   Author : James Carlsson; [2022]
   Keywords : Xylan; Wood; Solubility; Dynamic Light Scattering; Filtration; Xylan; Trä; Löslighet; Dynamisk ljusspridning; Filtrering;

   Abstract : Lösligheten av xylaner utvunna från trä undersöktes med Dynamisk Ljusspridning i syfte att observera eventuella förändringar i hydrodynamisk volym och ζ-potential. Xylaner extraherade från bok, björk och gran användes, där alkalisk extraherad bok erhölls kommersiellt och prover från björk och gran extraherades i förhand med subkritiskt vatten och alkalisk extraktion.

5. 4. A comparison of different orthogonal techniques for the investigation of the conformational stability of NIST mAb in liquid formulations

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

   Author : Madeleine Andersson; [2020]
   Keywords : Pharmaceutical technology; Läkemedelsteknologi; Biology and Life Sciences; Chemistry; Technology and Engineering;

   Abstract : A great challenge during early development of medicinal antibodies is to determine the stability of the candidates. This is required to be able to select the candidates with the greatest developability. READ MORE

6. 5. Dewatering Cellulose Nanofibril Suspensions through Centrifugation

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Jennifer Astorsdotter; [2017]
   Keywords : Cellulose nanofibrils; Microfibrilated cellulose; Centrifugation; Dewatering; Fiber suspension; Cellulosa nanofibriller; CNF; Microfibrilerad cellulosa; MFC; Centrifugering; Avvattning; Fibersuspension.;

   Abstract : Cellulose nanofibrils (CNF) is a renewable material with unique strength properties. A difficulty in CNF production is that CNF suspensions contain large amounts of water. If CNF suspension volume can be decreased by dewatering facilitated by centrifugation, then transportation costs and storage costs can be reduced. READ MORE
