    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

  3. 2. Organic electrochemical transistor

    Författare :David Nilsson; Xavier Crispin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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.
