1. Electrochemical monitoring of living cells
Abstract : This thesis presents the utilization of electroanalytical methods for analysis of dynamic cellular processes such as exocytosis, intracellular redox reactions and cell surface interactions. Microchips have been designed and manufactured with the purpose of monitoring dopamine exocytosis from single or a small ensemble of PC12 cells. READ MORE

3. lac of Time : Transcription Factor Kinetics in Living Cells
Abstract : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. READ MORE

4. Ultrasonic Handling of Living Cells in Microfluidic Systems
Abstract : Microfluidic chips have become a powerful tool in research where biological cells are processed and/or analyzed. One method for contactless cell manipulation in microfluidic chips that has gained an increasing amount of attention the last decade is ultrasonic standing wave (USW) technology. READ MORE
