4. 18. New Bioanalytical Approaches, Magneto Immunoassays and SIRE Technology Based Biosensors

   Författare :Kirstin Kriz; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; antigens; superparamagnetic nanoparticles; magnetic inductance transducer; competitive magneto immunoassay; enzymes; metabolites; differential measurements; SIRE; biosensor;

   Sammanfattning : This thesis presents two new technologies, SIRE technology based biosensors and magneto immunoassays, which can be used for bioanalytical applications. One of the main problems associated with biosensor technology is the instability of the recognition element since it is of biological origin and thus, has a limited lifetime. LÄS MER

   Sammanfattning : Biomolecular interaction analysis to determine the kinetics and affinity between interacting partners is important for the fundamental understanding of biology, as well as for the development of new pharmaceutical substances. A quartz crystal microbalance instrument suitable for kinetics and affinity analyses of interaction events was developed. LÄS MER

7. 20. 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
