  2. 21. Ultrasonic Enrichment of Microparticles in Bioaffinity Assays

    Author : Martin Wiklund; KTH; []
    Keywords : analytical chemistry; biochemistry; acoustics; biomedical engineering;

    Abstract : This Thesis describes applications of standing-waveultrasonic traps for sensitive biomedical analysis. Two majorapproaches have been investigated where functionalizedmicroparticles are employed in bioaffinity assays. READ MORE

  4. 22. Isotope enrichment by countercurrent electromigration in molten salts

    Author : Arnold Lundén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A series of isotope enrichments by electromigration in molten saltslias been carried out during the last, years. The running conditions aresummarized in table 1 and the enrichments achieved are given intables 2—13. Practical details such as the arrangement of the electricalcircuits and the construction of the separation columns are discussed. READ MORE

  6. 24. Enrichment and Separation of Phosphorylated Peptides on Titanium Dioxide Surfaces : Applied and Fundamental Studies

    Author : Anna I. K. Eriksson; Anders Hagfeldt; Katarina Edwards; Victor Agmo Hernández; Hubert Girault; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Posttranslational modification; Phosphorylation; Mass spectrometry; MALDI; Adsorption; QCM-D; Physical Chemistry; Fysikalisk kemi;

    Abstract : Protein phosphorylation is a very common posttranslational modification (PTM), which lately has been found to hold the keyrole in the development of many severe diseases, including cancer. Thereby, phosphoprotein analysis tools, generally based on specific enrichment of the phosphoryl group, have been a hot topic during the last decade. READ MORE

  7. 25. Clues to galaxy evolution from spectroscopic observations of Galactic centre stars

    Author : Brian Thorsbro; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical abundances; Late-type stars; Star clusters; Galactic center; Galaxy chemical evolution; Chemical enrichment;

    Abstract : In this work we present results from spectroscopic observations of Galactic centre stars. High resolution stellar spectroscopy can be used to determine accurate stellar metallicities and abundances. Observing stars in the Galactic centre is challenging due to extreme extinction. READ MORE
