   Sammanfattning : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

3. 2. Microscopy-based single-cell in vitro assays for NK cell function in 2-D and 3-D

   Författare :Per Erik Olofsson; Björn Önfelt; Khakoo Salim; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Physics; Biologisk fysik;

   Sammanfattning : Natural killer (NK) cells are effector cells of the innate immune system that are responsible for mediating cellular cytotoxicity against virally infected or neoplastically transformed cells. NK cell subsets are defined by their expression of certain cell-surface markers, and are usually related to activation and developmental status. LÄS MER

4. 3. An insight into the metabolism of New Psychoactive Substances : Structural elucidation of urinary metabolites of synthetic cannabinoids and fentanyl analogues using synthesized reference standards

   Författare :Jakob Wallgren; Johan Dahlén; Peter Konradsson; Xiongyu Wu; Mogens Johannsen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. LÄS MER

5. 4. Biochip design based on tailored ethylene glycols

   Författare :Andréas Larsson (Kaiser); Bo Liedberg; Tommy Nylander; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biosensor; biochip; poly ethylene glycol ; self-assembled monolayer; photopolymerisation; microarray; biomolecular interaction; explosives detection; Physics; Fysik;

   Sammanfattning : Studies of biomolecular interactions are of interest for several reasons. Beside basic research, the knowledge gained from such studies is also very valuable in for example drug target identification. Medical care is another area where biomolecules may be used as biomarkers to aid physicians in making correct diagnosis. LÄS MER

7. 5. Polyester scaffold: Material design and cell-protein-material interaction

   Författare :Staffan Dånmark; Anna Finne-Wistrand; Ann-Christine Albertsson; Kamal Mustafa; Pentti Tengvall; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Tissue engineering has emerged as a valid approach for the regeneration and restoration of bone defects. The concept of bone tissue engineering includes degradable scaffolds, osteogenic cells and osteoinductive growth factors either alone or in any combination of these three. LÄS MER
