2. 1. Push the limitations of crystal structure determination by 3D electron diffraction : From inorganic porous materials to biomolecules

   Author : Jingjing Zhao; Xiaodong Zou; Hongyi Xu; Tim Grüne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; 3D electron diffraction; cryo-EM specimen preparation; structure determination; porous materials; biomolecules; fysikalisk kemi; Physical Chemistry;

   Abstract : Structure elucidation is fundamental to understanding the chemical and physical properties of a material. Three-dimensional electron diffraction (3D ED) has shown great power for structure determination of nanometer- or submicrometer-sized crystals that are either too small or too complex for X-ray diffraction.

4. 2. Radiohalogenation of biomolecules : An experimental study on radiohalogen preparation, precursor synthesis, radiolabeling and biodistribution

   Author : Jacek Koziorowski; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

   Abstract : Radiohalogens are widely used in nuclear medicine, both as tool for diagnostic in vivo imaging and inradionuclide therapy. This study deals with the use of radiohalogens; separation, precursor synthesis, labeling and biological behavior. READ MORE

5. 3. Fluorescence studies of complex systems : organisation of biomolecules

   Author : Denys Marushchak; Lennart B.A. Johansson; Alexander Lyubartsev; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Spatially Controlled Covalent Immobilization of Biomolecules on Silicon Surfaces

   Author : Elisabeth Pavlovic; Sven Oscarsson; Marcus Textor; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; silicon oxide; electrooxidation; sulfur; nanotechnology; self-assembled monolayers; atomic force microscopy; electron spectroscopy for chemical analysis; biomolecules; covalent immobilization; reversibility; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The work described in this thesis aims to achieving surface patterning through chemical activation of thiolated silicon oxide surfaces, resulting in a spatially controlled covalent immobilization of biomolecules with high resolution.Existing chemical methods to immobilize molecules on surfaces do not reach below the micrometer scale while the ones allowing for spatial control mostly lead to non-covalent adsorption of molecules on surfaces, or require several successive chemical reactions to obtain the final covalent immobilization.
