  1. 1. Flow cytometry for bioprocess control

    Author : Fredrik Wållberg; KTH; []
    Keywords : flow cytometry; partec pas; propidium iodide;

    Abstract : 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. READ MORE

  2. 2. A Biotechnology Perspective on Silicon Nanowire FETs for Biosensor Applications

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

    Abstract : 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. READ MORE

  3. 3. Fossilized microorganisms in volcanic rocks from sub-seafloor environments

    Author : Magnus Ivarsson; Nils Holm; Sten Lindblom; Curt Broman; Harald Furnes; Stockholms universitet; []

    Abstract : 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. READ MORE

  4. 4. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    Author : Lisa Mårtensson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. READ MORE

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

    Author : Ninwe Maraha; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : 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. READ MORE
