    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Simultaneous detection; Bienzyme electrode; Amperometric biosensors; Cellular models; Analytisk kemi; Electrochemistry; Elektrokemi;

    Sammanfattning : Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. LÄS MER

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

    Sammanfattning : 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).
