  2. 6. Molecular Diagnostics Using Volume-Amplified Magnetic Nanobeads : Towards the Development of a Novel Biosensor System

    Author : Mattias Strömberg; Maria Strømme; Peter Svedlindh; Mikkel Fougt Hansen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic Biosensors; Ferrofluid; Biofunctionalisation; Ferrofluidic Aging; Interbead Interactions; Magnetic Nanobeads; Complex Magnetisation; Brownian Relaxation; Padlock Probes; Rolling Circle Amplification; Engineering physics; Teknisk fysik;

    Abstract : Micro- or nanometer sized magnetic particles (beads) currently have a vast range of life science applications in, for example, bioseparation techniques, cancer therapy, development of contrast agents and biosensing techniques. In the latter field, magnetic beads offer several unique advantages, including minimal background signals, physical and chemical stability and low manufacturing costs. READ MORE

  4. 7. Nuclear Magnetic Relaxation in Micellar Solution and Lyotropic Liquid Crystals. Tools and Applications

    Author : Ruslan Sitnikov; KTH; []
    Keywords : NMR; NMR relaxation dispersion; NMR spectrometer; low NMR frequencies; NMR duplexer; NMR preamplifier; NMR lock; surfactant systems; micellar solutions; lyotropic liquid crystals; cubic mesophase;

    Abstract : Structurally, this Thesis is divided into two parts thatdescribe (i) the hardware development for NMR relaxationstudies and (ii) its applications for studies of the surfactantsystems.The developed hardware solutions allow to expand thefrequency range covered by conventional NMR spectrometers tomake NMR experiments feasible at resonance frequencies down to100 kHz.

  5. 8. Laser cooling mechanisms and Brownian motors in optical lattices

    Author : Peder Sjölund; Anders Kastberg; Svante Jonsell; Chris Westbrook; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical physics; Optisk fysik;

    Abstract : Denna avhandling innefattar såväl experimentella som numeriska studier av laserkylda atomer i optiska kristallgitter. Bland annat har laserkylningsprocesser studerats, där atomers rörelser i optiska kristallgitter har uppvisat andra typer av bakomliggande mekanismer än de som tidigare förutsågs genom “Sisyfoskylningsmodellen”.

  6. 9. Heterogeneous Materials - Diffusion, Laplace spectrum and NMR

    Author : Matias Nordin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; perturbation; nmr; diffusion; laplace operator; spectrum; heterogeneous materials;

    Abstract : Relations to the effective diffusion constant and the relaxation rate of the time-dependent diffusion coefficient for porous systems are derived from the Laplace operator spectrum. The Padé approximation is then explained in terms of the Laplace operator spectrum. READ MORE

  7. 10. Carbohydrate dynamics and interactions studied by NMR spectroscopy

    Author : Olof Engström; Göran Widmalm; Niklas Hedin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The combination of NMR spectroscopy and molecular dynamics (MD) simulations are powerful tools in the studying of bioorganic molecules in solution. In this thesis two such studies are presented with focus on the NMR aspect. READ MORE
