1. 11. Development and Application of Enzyme- and Antibody-based Assays with Emphasis on Selectivity, Sensitivity and Stability

   Författare :Catalin Nistor; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stability; sensitivity; selectivity; cross-reactivity; sample matrix effects; environmental pollutants; enzyme biosensor; immunoassay; Analytical chemistry; Analytisk kemi;

   Sammanfattning : 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. 12. The Role of Odor and Sensory Irritation in Human Chemical Sensitivity

   Författare :Li Zheng; Birgitta Berglund; Staffan Hygge; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Odor and irritation detection; recognition; threshold; choice theory; intensity; chemical sensitivity; threshold; and sensitivity index.; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : The main objective of this thesis is to apply complimentary psychophysical theories and methods to investigate human perception of odor and sensory irritation of chemical compounds present in indoor air. Three psychophysical theories: Signal Detection Theory (SDT), Threshold Theory and Luce’s Choice Theory (CT) were applied to measure detection and recognition of odor and sensory irritation of two odorous irritants (pyridine and formaldehyde) by using the method of constant stimuli.
