12. Analysis of drugs and proteins in biological matrices, using different types of sample preparations and mass spectrometry
Abstract : This thesis describes bioanalysis of small and large molecules in biological matrices and includes screening of illegal drugs in urine with high resolution mass spectrometer, bioanalysis of MTH1 inhibitors in mice plasma and quantification of proteins in plasma and cell lysates.Screening of illegal drugs was based on high resolving power mass spectrometer (QTOF) and the results were compared to immunoassays.

13. Novel Microextraction Techniques for Bioanalysis of Neurotransmitters and Biomarkers in Biological Fluids
Abstract : Sample preparation (sample pre-treatment) is the initial step and an essential part in bioanalysis procedure. The main role of sample preparation is to extract and transfer the analyte(s) of interest from a complex matrix to a purified media such as a pure solvent for analysis and quantification. READ MORE

14. Amperometric biosensors of food analysis relevance: Emphasis on the neurotoxin beta-ODAP in grass pea
Abstract : Enzyme-based amperometric biosensors have been developed and characterized in flow systems for a variety of analytes such as [beta]-N-oxalyl-[alfa],[beta]-diamionpropionic acid ([beta]-ODAP), L-glutamate, glucose, lactate, and sucrose, that have food analysis relevance. The principle of enzyme "wiring" using polymeric mediators poly(1-vinylimidazole) {(Os-4, 4' dimethylbipyridyl)2Cl3+/2+} and poly(4-vinlypyridine {Os(N,N'-dimethyl-2,2'-biimidazole)3}3+/2+ has been employed in most of the sensors developed, which resulted in the fabrication of sensitive, stable and reproducible biosensors with carbonaceous electrodes (spectrographic graphite and glassy carbon).

15. Development of Methods for Phase System Characterization in Liquid Chromatography
Abstract : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. READ MORE
