  1. 6. Functional aspects of cellobiose dehydrogenase Applications for biosensor development

    Författare :Leonard Stoica; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; Analytisk kemi; Analytical chemistry; bioelectrochemistry; direct electron transfer; lactose biosensor;

    Sammanfattning : Electrochemcial investigations were conducted for elucidating and understanding the relation between the various electron transfer processes occurring in cellobiose dehydrogenase (CDH) bound to an electrode surface. Substrate inhibition caused by cellobiose was proven to act in competition with the electron transfer to a two-electron acceptor and under a partial inhibition mechanism for the internal electron transfer process.

  3. 7. Long-term follow-up in children born with congenital diaphragmatic hernia

    Författare :Elin Öst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Congenital diaphragmatic hernia (CDH) is a developmental defect which occurs in approximately 1 per 3000 births. The incomplete development of the diaphragm early in gestation allows abdominal viscera to herniate into the thoracic cavity. The malformation differs in size and can occur on either one or both sides, but most commonly on the left. LÄS MER

  4. 8. Improving the biocatalyst. Engineering of fungal oxidoreductases and thin-film electrodes for improvement of membraneless biofuel cells and carbohydrate biosensors

    Författare :Roberto Ortiz; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellobiose dehydrogenase; pyranose dehydrogenase; biosensor; enzymatic biofuel cell; carbon nanotubes; gold nanoparticles; direct electron transfer; flow-injection analysis; diazonium salts; self-assembled monolayers;

    Sammanfattning : This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying the bioelement or by modifying the electrode. LÄS MER

  5. 9. 2nd and 3rd generation electrodes for biosensors and biofuel cells

    Författare :MNadeem Zafar; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER

  7. 10. Role of ion and water channels for lung growth in congenital diaphragmatic hernia

    Författare :Andreas Ringman Uggla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Early lung development is based on a continuous cross-talk of growth and transcription factors between the developing lung bud and the surrounding parenchyma. Throughout fetal life, pulmonary growth and differentiation depend on Cl- driven lung liquid secretion. LÄS MER
