  1. 1. Development of a Bioelectronic Tongue -Applications for Wastewater Analysis

    Författare :Eva Dock; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; screen-printed electrode; multivariate data analysis; wastewater; Analytical chemistry; electronic tongue; biosensor array; amperometric;

    Sammanfattning : A bioelectronic tongue has been developed for applications in wastewater analysis. The development of a biosensor array with complex signal analysis started from the idea of using group-selective phenol biosensors (tyrosinase and horseradish peroxidase) with chemometric analysis for signal processing.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER

  4. 3. New Electrochemical Tools to Study Exocytosis

    Författare :Joakim Wigström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; amperometry; QCM-D; micro electrode array; large dense core vesicles; chromaffin cells; PC-12 cells; microelectrode; exocytosis; electrochemical cytometry; electrochemical imaging; acetylcholine; endocytosis; nanoparticles; enzyme biosensor; microfabrication;

    Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER

  5. 4. Affinity biosensors with porous and multi-array surfaces

    Författare :Danny van Noort; Otto Wolfbeis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Affinity biosensing is one of many analytical techniques that have high potential for the detection of drug leads. In this thesis the use of ellipsometry, surface plasmon resonance (SPR) as well as quartz crystal microbalance (QCM) as screening methods in drug discovery are presented. LÄS MER

  7. 5. Development of Nanoimprint Lithography for Fabrication of Electrochemical Transducers

    Författare :Marc Beck; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrochemistry; interdigitated array; anti-adhesion; anti-sticking; stamp; mold; monolayer deposition; Fysik; post-imprint processes; Physics; transducer; nanoimprint lithography; sensor; Fysicumarkivet A:2003:Beck;

    Sammanfattning : This thesis gives an overview about the current status of nanoimprint lithography, a relatively new nanofabrication tool. The technology is capable for parallel mass production of nm-structured features having a resolution below 10 nm and is usable with high throughput on full wafer scale. LÄS MER
