1. Condensation of DNA for Gene Delivery: Studies on Vector-Nucleic Acid Interactions and Transfection Efficiency
Abstract : This thesis concerns the delivery of nucleic acids into cells and tissues with the aim to change or correct gene expression. The field of gene delivery has the ultimate goal of producing genetic drugs for clinical applications, and the activity in this area is intense although so far the use is limited to research purposes.

2. Cell-Penetrating Penetratin Peptides - Mechanistic Studies on Uptake Pathways and DNA Delivery Efficiency
Abstract : Delivery of gene-targeted drugs is limited by the inherently poor capacity of nucleic acids to overcome the membrane barrier of the cell, and development of vectors that can promote uptake is therefore crucial. Cell penetrating peptides (CPPs) have emerged as promising vector candidates due to their ability to deliver a wide range of macromolecular cargos into cells. READ MORE

3. The Cyanobacterial Uptake Hydrogenase : Regulation, Maturation and Function
Abstract : With accellerating global warming and pollution problems a change of energy regime is necessary. Solar energy offers a clean and unlimited energy source of enormous potential. Due to it’s intermittenet nature solar energy must be stored - ideally in the chemical bond of a carrier molecule. READ MORE

4. Endocytosis of therapeutic macromolecules in tumor cells - Mechanistic aspects of the proteoglycan receptor function
Abstract : Novel therapeutics to combat cancer are urgently needed. Most current pharmacological therapies have severe side effects and are seldom curative. Macromolecular drugs, and in particular nucleic acid based drugs, offer a potential remedy for this situation. READ MORE

5. Optical Dyes for Visualization of Structure and Function of Biomolecules and Biological Membranes
Abstract : To visualize the structure and function of biomolecules and biological membranes in the cell, optical dyes are important tools where in particular fluorescent probes provide a sensitive and selective detection. When cellular compartments are investigated it is crucial that the probe selectively binds to the area of interest and not exhibits unspecific binding affinity. READ MORE
