1. 1. Combining Nanoplasmonics and Nanofluidics for Single Particle Catalysis

   Författare :David Albinsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; heterogeneous catalysis; CO oxidation; plasmonic sensing; dark field scattering spectroscopy; nanocatalyst; LSPR; single particle catalysis; nanofluidics; nanoreactor; Cu oxidation;

   Sammanfattning : Nanoparticles are, due to their large exposed surface area, widely used in the field of heterogeneous catalysis where they accelerate and steer chemical reactions. Although catalysis has been known about for centuries, the scrutiny of catalysts under realistic application conditions is still a major challenge. LÄS MER

3. 2. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective

   Författare :Robin Öz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-molecule; Protein; NHEJ; Dynamic; DNA repair; HR; Biomolecule interactions; Microscopy; Fluorescence; Nanofluidics;

   Sammanfattning : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. LÄS MER

4. 3. Nanofluidics as a tool for parallelized single nanoparticle characterization: Fluorescence single nanoparticle catalysis and size determination through 1D Brownian motion

   Författare :Sune Levin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dark field microscopy; single nanoparticle catalysis; heterogenous catalysis; particle tracking; Brownian motion; fluorescence microscopy; nanofluidics;

   Sammanfattning : Nanoparticles exist widely in nature and are objects of study in many scientific disciplines due to their high performance in a wide range of applications. With modern techniques that facilitate creating and shaping of nanoparticles into ever more complex shapes and compositions, characterization of particle properties is essential. LÄS MER

5. 4. Biophysical studies of DNA binding – by the large filament-forming protein Rad51 and the small minor-groove binder Hoechst 33258

   Författare :Louise Fornander; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rad51; Linear Dichroism; DNA; Isothermal Titration Calorimetry.; Spectroscopy; Nanofluidics; Hoechst 33258; DNA-binding ligands;

   Sammanfattning : Mechanistic insight into the nature of DNA-binding ligands is crucial for both drug development as well as understanding more complex biological reactions that take place in the cell. In this Thesis, two rather different DNA-binding molecules are considered: 1. LÄS MER
