1. 1. Frequency comb Brillouin microscopy

   Författare :Felipe Ademir Alemán Hérnandez; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brillouin light scattering; optics; spinwave spectroscopy; phonon spectroscopy; microscopy; Fabry-Perot interferometer; Frequency comb;

   Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER

5. 4. Optical Mapping of Bacterial Plasmids

   Författare :Vilhelm Müller; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; competitive binding; optical mapping; fluorescence microscopy; DNA; plasmids; CRISPR Cas9; antibiotic resistance; nanofluidics; single-molecule;

   Sammanfattning : Bacteria that have acquired resistance to antibiotics represent one of the largest threats to human health and modern health care. The genes encoding resistance are frequently spread via the transfer of plasmids, which are circular double stranded DNA molecules separate from the chromosomal DNA of the bacteria. LÄS MER

7. 5. Development of Nonlinear Microscopy for Studies of Metabolism and Tissue Engineering

   Författare :Madeleine Åkeson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; imaging; bacterial cellulose; nonlinear microscopy; Saccharomyces cerevisiae; yeast; C. elegans; Microscopy; lipid storage;

   Sammanfattning : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.
