  1. 1. Flow cytometry for bioprocess control

    Författare :Fredrik Wållberg; KTH; []
    Nyckelord :flow cytometry; partec pas; propidium iodide;

    Sammanfattning : During bio-technical processing it is important to monitorbiological parameters such as cell growth, viability andproduct formation. Many of the analyses traditionally used areslow to perform and provide only average data for thepopulation. LÄS MER

  3. 2. Blood protein coated model biomaterials : preparation, and cell and tissue response

    Författare :Eva Jansson; Hans Elwing; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Solid biomaterials are widely used in bone and in soft tissue applications. Problems may then arise due to a prolonged inflammation in the proximity of the implant, resulting in the formation of a fibrous capsule and a low vascularisation near the interface. LÄS MER

  4. 3. A Biotechnology Perspective on Silicon Nanowire FETs for Biosensor Applications

    Författare :Nima Jokilaakso; Amelie Eriksson Karlström; Christer Wingren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The study of silicon nanowire-FET-based electronic biosensor applications is an emerging scientific field. These biosensors have the benefit of being theoretically extremely sensitive and reports of down to femtomolar (fM) levels of biomolecule detection have been reported. LÄS MER

  5. 4. Fossilized microorganisms in volcanic rocks from sub-seafloor environments

    Författare :Magnus Ivarsson; Nils Holm; Sten Lindblom; Curt Broman; Harald Furnes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfossils; hydrothermal systems; deep biosphere; Other earth sciences; Övrig geovetenskap; Mineralogy; Petrology and Geochemistry; mineralogi; petrologi och geokemi;

    Sammanfattning : Fossilized microorganisms are focused in this thesis. Such organisms have been observed in drilled basalt samples from the Emperor Seamounts in the Pacific Ocean collected during ODP (Ocean Drilling Program) Leg 197. LÄS MER

  7. 5. Studies of the physiological status of bacteria used for environmental applications

    Författare :Ninwe Maraha; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Today, it is difficult to study the physiological status of inoculants in complex environments, such as soil. In this thesis, we describe the combined use of marker genes and viability stains to determine the physiological status of the bacterial cells in pure cultures and in soil. LÄS MER
