1. Improved Neuropeptide Identification : Bioinformatics and Mass Spectrometry
Sammanfattning : Bioinformatic methods were developed for improved identification of endogenous peptides using mass spectrometry. As a framework for these methods, a database for endogenous peptides, SwePep, was created. It was designed for storing information about endogenous peptides including tandem mass spectra. LÄS MER
2. Mass Spectrometry-based Neuroproteomics : Deciphering the Human Brain Proteome
Sammanfattning : Mammalian brain is challenging to study due to its heterogeneity and complexity. However, recent advances in molecular imaging, genomics and proteomics have contributed significantly to achieve insights into molecular basis of brain function and pathogenesis of neurological disorders.

3. Laser-based absorption spectrometry : development of NICE-OHMS towards ultra-sensitive trace species detection
Sammanfattning : Laser-based absorption spectroscopy (AS) is a powerful technique for qualitative and quantitative studies of atoms and molecules. An important field of use of AS is the detection of species in trace concentrations, which has applications not only in physics and chemistry but also in biology and medicine, encompassing environmental monitoring, regulation of industrial processes and breath analysis.

4. Liquid Chromatography Coupled to Mass Spectrometry : Implementation of Chemometric Optimization and Selected Applications
Sammanfattning : Liquid chromatography (LC) coupled to mass spectrometry (MS) offers highly selective and sensitive analysis of a wide variety of compounds. However, the use of hyphenated experimental set-ups implies that many parameters may have an effect on the studied response. LÄS MER
5. Novel strategies to increase throughput and differentiate lipid isomers in mass spectrometry imaging : Development of computational tools and complex mass spectrometric methods for nanospray desorption electrospray ionization
Sammanfattning : In this thesis, method development for improved analyte identification and throughput in mass spectrometry imaging (MSI) is discussed. In MSI, the spatial distribution of analytes from a sample is determined and visualized, information about the detected molecules interaction within the sample can thereby the deduced. LÄS MER
