  4. 4. Characterization of biological nanoparticles using evanescent field sensing

    Författare :Mattias Sjöberg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; label-free; protein corona; mass quantification.; liposomes; single-particle; SPR; Waveguide scattering microscopy;

    Sammanfattning : In light of the increasingly realized importance of nanoparticle-based biological processes, in biology as well as in technological applications, there is a need of analysis methods capable of accurately quantifying different characteristics and processes involving these elusive entities. The aim of this thesis is the development and utilization of surface-based bioanalytical sensing methods for quantitative characterization of biological nanoparticles, most of which being based on surface-confined evanescent-field illumination.

  5. 5. Utilization of waste materials for extraction of strategic metals : a biogeochemical approach

    Författare :Viktor Sjöberg; Stefan Karlsson; Bert Allard; Mattias Bäckström; Christian Ekberg; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biogeochemistry; ICP-QMS; MP AES; strategic metals; vanadium; uranium; mine waste; steel slag; shale residues; Enviromental Science; Miljövetenskap;

    Sammanfattning : Worldwide the modern society produces vast amounts of waste materials containing strategic and valuable metals. Some of them are of substantial economic or environmental significance if controlled recovery of metals can be performed or if uncontrolled release to the environment occurs. LÄS MER
