1. Rapid sample preparation and bioanalytical techniques for efficient screening of organic pollutants in the environment
Abstract : Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need for simpler techniques. The work underlying this thesis assessed the potential utility of more convenient sample preparation and bioanalytical techniques for rapidly screening various environmental matrices that could be useful complements to higher resolution methods.

2. Development and Application of Enzyme- and Antibody-based Assays with Emphasis on Selectivity, Sensitivity and Stability
Abstract : This thesis presents the development, optimisation, and various applications of enzyme-based biosensors and immunoassays, mainly with relevance to environmental analysis. the thesis discusses problems and possible solutions associated with selectivity, sensitivity and robustness of such bioassays with emphasis on various immunoasssay configurations for determination of surfactants, phenols, or drugs, and amperometric biosensors based on enzymes (e.

3. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS
Abstract : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

4. Enzymatic and Immunological Detection Principles for Environmental and Biological Applications
Abstract : The aim of the thesis was to develop new analytical detection principles based on enzymatic and immunological reactions for sensitive, selective, cost-effective and high sample through-put detection devices. The thesis presents the basic elements and reaction paths necessary for the construction and development of enzyme based amperometric biosensors and immunoassays. READ MORE
