   Abstract : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. READ MORE

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

   Author : Yirgalem Yigzaw; Centrum för analys och syntes; []
   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).

5. 3. Biosensors and Automation for Bioprocess Monitoring and Control

   Author : M A Kumar; Bioteknik; []
   Keywords : online monitoring; ELISA; immunosensor; flow injection; Biosensor; bioprocess; control; environmental;

   Abstract : Bioprocess monitoring and control is a complex task that needs rapid and reliable methods which are adaptable to continuous analysis. Process monitoring during fermentation is widely applicable in the field of pharmaceutical, food and beverages and wastewater treatment. READ MORE

6. 4. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection

   Author : Niklas Larsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microdialysis; Liquid chromatography; Flow injection; Polyelectrolytes; Carbohydrate; Mediator; Dehydrogenase; Peroxidase; Oxidase; Enzyme; Amperometric detection; Carbon paste; Biosensor; Graphite electrode; On-line monitoring; Analytical chemistry; Analytisk kemi;

   Abstract : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. READ MORE

7. 5. Amperometric Carbon Paste Biosensors Based on Horseradish Peroxidase and Oxidases

   Author : Vijayakumar Rajendran; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; on-line monitoring; l-lactate; glucose; ethanol; Biosensor; Carbon paste; Analytisk kemi;

   Abstract : Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. READ MORE
