6. New Techniques for Sample Preparation in Analytical Chemistry : Microextraction in Packed Syringe (MEPS) and Methacrylate Based Monolithic Pipette Tips
Sammanfattning : Sample preparation is often a bottleneck in systems for chemical analysis. The aim of this work was to investigate and develop new techniques to address some of the shortcomings of current sample preparation methods. LÄS MER
7. Immuno-affinity interactions in sample preparation and analysis
Sammanfattning : Immuno-affinity interactions (antibody-antigen) belong, together with enzyme-inhibitor/substrate/coenzyme; oligosaccharide-lectin; DNA/RNA-protein interactions etc, to the class of bio-recognition. Immuno-affinity is widely used for analysis in immunoassays with numerous applications in a variety fields (i.e. LÄS MER
8. Microfluidic bases sample preparation for blood stream infections
Sammanfattning : Microfluidics promises to re-shape the current health-care system by transferring diagnostic tools from central laboratories to close vicinity of the patient (point-of-care). One of the most important operational steps in any diagnostic platform is sample preparation, which is the main subject in this thesis. LÄS MER
9. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations
Sammanfattning : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).

10. Acoustofluidic rare cell sample preparation
Sammanfattning : Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. LÄS MER
