  2. 1. Amperometric Biosensors for Detection of Analytes in Cellular Models

    Author : Jaime Castillo Leon; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Simultaneous detection; Bienzyme electrode; Amperometric biosensors; Cellular models; Analytisk kemi; Electrochemistry; Elektrokemi;

    Abstract : 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. READ MORE

  4. 2. 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

  5. 3. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

    Author : Lesedi Lebogang; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microcystins; Drinking water; Adda-specific monoclonal antibodies; Biosensors; Capacitive; Amperometric; Flow-ELISA; Microcontact imprinting;

    Abstract : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. READ MORE

  6. 4. Enzymatic and Immunological Detection Principles for Environmental and Biological Applications

    Author : Elisabeth Burestedt; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; interleukin-8; D-ammino acids; carbon paste; flow immunoassays; Amperometric biosensors; phenols; Analytisk kemi;

    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

  7. 5. Amperometric biosensor-based microsystems for detecting analytes of biomedical importance

    Author : Szilveszter Gaspar; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; microelectrodes; enzyme electrodes; SECM; biomedicine; µTAS; microsystems; biosensors; electrochemical detection; Bioteknik;

    Abstract : Monitoring in the biomedical field is rapidly emerging as the most important application area of miniaturized analytical devices. Diagnostics, disease monitoring, drug development, and medical research are important areas taking full advantage of the short response time, reduced sample consumption, low costs, and reduced power requirements of miniaturized analytical tools.
