3. 2. Structure evolution of spin-coated phase separated EC/HPC films

   Författare :Pierre Carmona; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Structure evolution of phase-separated EC/HPC films for controlled drug release

   Författare :Pierre Carmona; Chalmers tekniska högskola; []
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

5. 4. Quantitative methods for diffusion measurements in fluorescence microscopy

   Författare :Marco Longfils; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cross-validation.; single particle tracking; Confocal laser scanning microscopy; raster scan; correlation spectroscopy; mixture models; diffusion;

   Sammanfattning : In this work, statistical methods are developed for mapping mass transport locally based on images collected using a confocal laser scanning microscope. Besides presenting raster image correlation spectroscopy as an established method in fluorescence microscopy, we introduce a single particle tracking method which takes advantage of the raster scanning of the image in a confocal microscope.

7. 5. Raster Image Analysis of Diffusion via Single Particle Methods

   Författare :Marco Longfils; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; single particle tracking; raster scan; confocal laser scanning microscopy; image correlation spectroscopy; raster scan;

   Sammanfattning : Soft biomaterials are widely used in many application areas, spanning from packaging materials to pharmaceuticals. To enhance their functionalities, understanding the interplay between microstructure and mass transport properties in these materials is fundamental. LÄS MER
