1. Development and Validation of Bioanalytical Methods : Application to Melatonin and Selected Anti-Infective Drugs
Sammanfattning : This thesis describes bioanalytical methods for measuring melatonin and some anti-infective drugs in biological fluids. Solid-phase extraction (SPE) or protein precipitation was used for enrichment and purification of the analytes and Liquid Chromatography (LC) was used to analyze the samples. LÄS MER
2. Models of chemical bonding : Representations Used in School Textbooks and by Teachers and their Relation to Students´Difficulties in Understanding
Sammanfattning : This thesis focuses on how school textbooks and teachers present models of chemical bonding in upper secondary schools in Sweden. In science, as well as in science education, models play a central role, but research has shown that they often are difficult for students to understand. LÄS MER
3. Development of Field-adapted Analytical Methods for the Determination of New Antimalarial Drugs in Biological Fluids
Sammanfattning : This thesis deals with the development of analytical methods for the determination of new antimalarial drugs in biological fluids. The goal was to develop methods that facilitate clinical studies performed in the field, such as capillary blood sampling onto sampling paper. LÄS MER
4. Methods for structural studies of an antibody, screening metabolites in rat urine and analysis of spent cell cultivation media using LC/ESI-MS and chemometrics
Sammanfattning : This thesis describes bioanalytical methods for generating fingerprints of biological systems for extracting relevant information with (protein) drugs in focus. Similarities and differences between samples can reveal the hidden relevant information, which can be used to optimize the production and facilitate the quality control of such protein drugs during their development and manufacture.
