  1. 1. New Electrochemical Tools to Study Exocytosis

    Author : Joakim Wigström; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Organic electrochemical transistor

    University dissertation from Linköping : Linköpings universitet

    Author : David Nilsson; Xavier Crispin; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Conducting polymers entered the research field in late 70's and investigations regarding printable electronics started a decade later. In this thesis printable organic electrochemical transistors (OECT) will be treated. Conjugated polymers can be switched between a high conducting and low conducting state in electrochemical cells.

  5. 5. Microdialysis Sampling, Electrochemical Detection and Mass Spectrometry of Carbohydrates in Monitoring Bioprocesses

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Nelson Torto; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; monosaccharides; membrane; IPED; ion spray; probe internal geometry; extraction fraction; electrochemical oxidation; electrochemical detection; disaccharides; desalting; carbohydrates; bioprocess monitoring; Cu; APCI; Au; MS; oligosaccharides; PAD; PEI; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis addresses; (1) the microdialysis experiment, application and methodology to maximise its performance when sampling from enzymatic bioprocesses, (2) electrochemical detection and electrochemical oxidation of carbohydrates on Au as well as Cu electrodes in alkaline solutions, and (3) coupling and maximising the performance of a microdialysis sampling based high performance anion exchange chromatography-integrated pulsed electrochemical detection-mass spectrometry system. Studies were carried out to investigate the effect of temperature, analyte as well as biomatrix complexity, analyte concentration, permeability factors, protein(enzyme)-membrane interaction and membrane material on the performance of microdialysis sampling.
