  2. 1. Fluorescence Properties of Quantum Dots and Their Utilization in Bioimaging

    Author : Hao Xu; Ying Fu; Hjalmar Brismar; Marina Zelenina; Mattias Goksör; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence; Microscopy; Bioimaging; Nanomaterial; cytotoxicity; mechanism; Biological Physics; Biologisk fysik;

    Abstract : Quantum dots (QDs), especially colloidal semiconductor QDs, possess properties including high quantum yields, narrow fluorescence spectra, broad absorption and excellent photostability, making them extremely powerful in bioimaging. In this thesis, we studied the fluorescence properties of QDs and attempted multiple ways to boost applications of QDs in bioimaging field. READ MORE

  4. 2. Effects of humic substances and pH on the speciation and adsorption of cadmium, mercury and arsenic

    Author : Hao Xu; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The emission of acidifying substances to air causes not only immediate, easily observable effects on the environment, but also slowly emerging indirect effects. Among the latter, special attention has been given to changes in mobility and bioavailability of trace elements in the environment. READ MORE

  5. 3. Functional aspects of modified nucleosides in tRNA

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tRNA modification; frameshifting; Elongator complex; Elp1p; Prb1p; proteolysis; glioma; TRM6 61; PKCα;

    Abstract : Transfer ribonucleic acids (tRNAs) are extensively modified, especially their anticodon loops. Modifications at position 34 (wobble base) and 37 in these loops affect the tRNAs’ decoding ability, while modifications outside the anticodon loops, e.g. m1A58 of tRNAMeti, may be crucial for tRNA structure or stability.
