  2. 1. New Electrochemical Tools to Study Exocytosis

    Author : Joakim Wigström; Chalmers tekniska högskola; []
    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

  4. 2. Organic electrochemical transistor

    Author : David Nilsson; Xavier Crispin; Linköpings universitet; []
    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.
