5. 14. First As Probe, Then As Function - Fluorescence in Bio-inspired Nanotechnology

   Författare :Jonas Hannestad; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lipid membrane; bio-inspired; FRET; light-harvesting; spectroscopy.; fluorescence; nanotechnology; single molecule fluorescence spectroscopy; DNA;

   Sammanfattning : In this thesis, I demonstrate how fluorescence can be used in the context of bio-inspired nanotechnology, both as an indirect probe and as a function in itself. By combining principles and molecules from three different bio-molecular systems, DNA, bacterial light-harvesting complexes and cell membranes, I have constructed nano- and microscale systems for long-range excitation energy transfer, light-harvesting and reaction control.

7. 15. Amyloid Fibril Formation - Dye Detection and Effects of Lipids

   Författare :David Lindberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atomic force microscopy; fluorescence; Alzheimer’s disease; YOYO-1; amyloid fibrils; lipids; linear dichroism; FRET; circular dichroism; kinetics; Protein aggregation; insulin; thioflavin-T;

   Sammanfattning : Amyloid fibrils are long fibrillar homopolymers of self-assembled proteins. They can be formed by essentially any polypeptide, but are of particular interest because of their occurrence in several incurable and debilitating human diseases, e.g. Alzheimer’s disease (AD). LÄS MER
