2. 1. Applications of hydrodynamic forces for membrane chromatography

   Author : Björn Johansson Fast; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane chromatography; FRAP; Protein accumulation; Supported lipid bilayer; Microfluidics; SEEC; Diffusion; Hydrodynamic forces; Label-free;

   Abstract : Membrane proteins are proteins that reside in the cell membrane. Due to their position in the cell membrane, the barrier between the cell interior and exterior, they are vital to cell signaling. Moreover, the presence of membrane proteins in the cell's signaling pathways make membrane proteins important drug targets. READ MORE

4. 2. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

   Author : Niklas Lorén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

   Abstract : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. READ MORE

5. 3. Droplet microfluidics for high throughput biological analysis

   Author : Håkan Jönsson; Helene Andersson-Svahn; Andrew Griffiths; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Droplet microfluidics; High throughput biology; Single cell analysis; Hydrodynamic separation; Enzyme amplification; Fluorescence polarization; Microfabrication; Bioengineering; Bioteknik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Abstract : Many areas of biological research increasingly perform large-scale analyses.  In genomics the entire gene repertoire of an organism is analyzed.  Proteomics attempts to understand the function and expression patterns of all proteins in a cell or organism. READ MORE

6. 4. Structure evolution of spin-coated phase separated EC/HPC films

   Author : Pierre Carmona; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin-coating; controlled drug release; porous film; drug delivery; confocal laser scanning microscope; kinetics; phase separation mechanisms; cellulose; biopolymer; phase separation;

   Abstract : Porous phase-separated films made of ethylcellulose (EC) and hydroxypropylcellulose (HPC) are commonly used for controlled drug release. The structure of these thin films is controlling the drug transport from the core to the surrounding liquid in the stomach or intestine. However, detailed understanding of the structure evolution is lacking. READ MORE

7. 5. Structure evolution of phase-separated EC/HPC films for controlled drug release

   Author : Pierre Carmona; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electron microscopy; coarsening; cellulose; phase separation kinetics; drug delivery; phase separation mechanisms; porous film; biopolymer; controlled drug release; confocal laser scanning microscope; spin-coating.;

   Abstract : Porous phase-separated ethylcellulose/hydroxypropylcellulose (EC/HPC) films are used to control drug transport out of pharmaceutical pellets. The drug transport rate is determined by the structure of the porous films that are formed as the water-soluble HPC leaches out. READ MORE
