  1. 1. Amperometric biosensors of food analysis relevance: Emphasis on the neurotoxin beta-ODAP in grass pea

    University dissertation from Analytical Chemistry, Lund University

    Author : Yirgalem Yigzaw; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; Analytisk kemi; Analytical chemistry; neurotoxin; Amperometric biosensors; Lathyrus sativus;

    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).

    Abstract : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

  3. 3. Invasive and Non-Invasive Quantification of Cardiac Kinematics

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Katarina Kindberg; Matts Karlsson; Bjørn Skallerud; [2010]

    Abstract : The ability to measure and quantify myocardial motion and deformation provides a useful tool to assist in the diagnosis, prognosis and management of heart disease. Myocardial motion can be measured by means of several different types of data acquisition. READ MORE
