  1. 16. Bottom-up Fabrication of Functional DNA Nanostructures

    Författare :Erik Lundberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; click chemistry; gel electrophoresis; self-assembly; cross-linking; lipid membrane; fixation; linear dichroism; nanotechnology; spectroscopy; fret; dna; triplex recognition;

    Sammanfattning : This thesis demonstrates bottom-up fabrication of a fully addressable non-repetitive network on the nanometer scale, assembled by synthetic DNA molecules. Each side constitutes a unique sequence of 10 bases, i.e. 3. LÄS MER

  3. 17. Fixation of Functionalized DNA Nanostructures

    Författare :Erik Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; triplex recognition; dna; self-assembly; gel electrophoresis; nanotechnology; cross-linking; spectroscopy; fixation; fret; click chemistry;

    Sammanfattning : This thesis features results from two different studies on a fully addressable non-repetitive network on the nanometre scale, assembled by synthetic DNA molecules. A bio-inspired molecular approach, based on principles of self-assembly, has brought about a paradigm shift in nanoscience, from a top-down to a bottom-up perspective. LÄS MER

  4. 18. Fluorescence studies of complex systems : organisation of biomolecules

    Författare :Denys Marushchak; Lennart B.A. Johansson; Alexander Lyubartsev; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescence anisotropy; BODIPY; homo and hetero dimerisation; protein aggregates; protein polymer structures; actin polymerisation; FRET; donor–acceptor energy transfer DAET; donor-donor energy migration DDEM; homotransfer; Monte Carlo simulation; MC; Brownian dynamics; BD; Genetic Algorithm; GA.; Ganglioside GM1; Biophysical chemistry; Biofysikalisk kemi;

    Sammanfattning : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. LÄS MER

  5. 19. Neuroinflammation in Alzheimer's disease : Focus on NF-κB and C/EBP transcription factors

    Författare :Veronica Ramberg; Kerstin Iverfeldt; Josep Saura; Stockholms universitet; []
    Nyckelord :Alzheimer’s disease; neuroinflammation; NF-κB; C EBP; apoptosis; caspases; FRET; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

    Sammanfattning : Alzheimer's disease (AD) is the most common form of dementia among elderly. The disease is characterized by amyloid-β (Aβ) plaques, neurofibrillary tangles, loss of synapses and neurons and chronic neuroinflammation. LÄS MER

  7. 20. Lipid Vesicle Fusion: Investigation, Generation and Manipulation of Cell-Membrane Mimics

    Författare :Lisa Simonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; spreading lipid bilayers; cell mimic; micromanipulation; lipid bilayer; microfluidics; site-specificity; DNA; membrane-receptor interactions; total internal reflection fluorescence microscopy; model system; self-assembly; TIRF microscopy; FRET; exocytosis; vesicles; fluorescence resonance energy transfer; biomembranes; amperometry; membrane fusion;

    Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. In this work, cell-membrane mimics were constructed and evaluated as models for studies of the membrane-fusion process. LÄS MER
