1. 11. Enzymatic and Immunological Detection Principles for Environmental and Biological Applications

   Författare :Elisabeth Burestedt; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; interleukin-8; D-ammino acids; carbon paste; flow immunoassays; Amperometric biosensors; phenols; Analytisk kemi;

   Sammanfattning : The aim of the thesis was to develop new analytical detection principles based on enzymatic and immunological reactions for sensitive, selective, cost-effective and high sample through-put detection devices. The thesis presents the basic elements and reaction paths necessary for the construction and development of enzyme based amperometric biosensors and immunoassays. LÄS MER

3. 12. First Principles Studies of Carbon Based Molecular Materials

   Författare :Bin Gao; Yi Luo; Piero Decleva; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; first principles simulations; carbon based molecular materials; X-ray spectroscopies; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : The aim of this thesis was to investigate carbon based molecular materials at first principles levels. Special attention has been paid to simulations of X-ray spectroscopies, including near edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron, and X-ray emission spectroscopy, which can provide detailed information about core, occupied and unoccupied molecular orbitals of the systems under investigation.

4. 13. Thiol-Ene/Yne Adhesives for Tissue Fixation

   Författare :Viktor Granskog; Michael Malkoch; Philip Messersmith; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The utilization of adhesives in surgery has not reached its full potential and research in the field is encouraged by the surgeons’ desire for improved alternatives to today’s tissue fixation strategies. Here, adhesive resins based on thiol-ene coupling (TEC) chemistry or thiol-yne coupling (TYC) chemistry are exploited to develop tissue adhesives that cure fast and on-demand via photoinitiation.

5. 14. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS

   Författare :Patrik Önnerfjord; Reumatologi och molekylär skelettbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein identification; microchip IMER; microdispensing; MALDI-TOF MS; fluorescence polarization; flow immunoassay; pesticide immunoassays; phenol biosensor; restricted access media; SPE; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

7. 15. Selenium Compounds and Antioxidant Capacity in Bovine Milk. Studies on Glutathione Peroxidase, Bioavailability and Electrochemical Techniques

   Författare :Jun Chen; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; amperometry; voltammetry; antioxidant capacity; ileostomy; bioavailability; glutathione peroxidase; bovine milk; selenium;

   Sammanfattning : The efficacy and function of antioxidants have been intensively studied in foods and other biological systems in recent decades. This thesis concerns different aspects of the antioxidant properties of bovine milk, with emphasis on measurement of the total antioxidant capacity (TAC), the activity of the selenium-containing glutathione peroxidase (GSHPx), and the bioavailability of selenium from bovine milk in humans.
