1. Creating Ultrafast Biosensors for Neuroscience
Sammanfattning : Neuronal communication is the basis for all our brain function and relies on regulated exocytosis, a cell function that involves release of quantal amounts of neurotransmitters into the gap space between interconnected neurons to serve as chemical signals. To study exocytosis, which is a fast process that occurs on the timescale of sub-milliseconds to milliseconds, a toolbox of analytical methods has been developed where the electrochemical based techniques offer quantitative and sufficient high temporal recording speed.

2. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side
Sammanfattning : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. LÄS MER
3. Structure and Function of Cytochrome c Oxidase
Sammanfattning : Aerobic organisms, ranging from bacteria to humans, obtain their energy through the process of respiration. Electrons from the breakdown of food are transported through the membrane-bound enzyme complexes of the respiratory chain, to the terminal acceptor molecule, oxygen. LÄS MER
4. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection
Sammanfattning : 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. LÄS MER
5. Development of Ultra-fast Biosensors for Detection of Non-electroactive Neurotransmitters
Sammanfattning : During neuronal communication neurotransmitters are released through the process exocytosis that occurs on the time scale of sub-milliseconds to milliseconds. Neuronal activity by neurotransmitters that are non-electroactive cannot easily be monitored due to limitations in the temporal resolutions of the sensor probes for these analytes. LÄS MER
