1. Zwitterionic Separation Materials for Liquid Chromatography and Capillary Electrophoresis : Synthesis, Characterization and Application for Inorganic Ion and Biomolecule Separations
Sammanfattning : Liquid Chromatography (LC) and Capillary Electrophoresis (CE) are modern analytical techniques that play very important roles in many areas of modern science such as life science, biotechnology, biomedicine, environmental studies, and development of pharmaceutics. Even though these two techniques have existed and been subjected to studies for several decades, the developments of new separation materials for them are still very important till now in order to meet the different new demands for improvement from other disciplines in science.

2. Proton-Coupled Electron Transfer from Hydrogen-Bonded Phenols
Sammanfattning : Proton-coupled electron transfer (PCET) is one of the elementary reactions occurring in many chemical and biological systems, such as photosystem II where the oxidation of tyrosine (TyrZ) is coupled to deprotonation of the phenolic proton. This reaction is here modelled by the oxidation of a phenol covalently linked to a Ru(bpy)32+-moitey, which is photo-oxidized by a laser flash-quench method. LÄS MER
3. Carbon Nanotubes for Electronic Packaging: Growth, Novel Devices and 3D Networks
Sammanfattning : Carbon nanotubes (CNTs) have shown great potential of application in electronics because of their attractive physical properties, such as high surface-to-volume ratio, high electron mobility, high Young’s modulus, high thermal conductivity, low thermal expansion coefficient, etc. However, many obstacles are yet to be removed to use CNTs as building blocks in electronic systems.

4. Antibacterial surface coatings for biomedical applications
Sammanfattning : Over the past decades there has been a significant increase in the diversity and function of biomaterials. Today, medical practices utilize a large number of biomaterials in the form of medical devices and implants. However, one major obstacle that limits the efficiency of biomaterials is their susceptibility to develop infection. LÄS MER
5. DNA Tools and Microfluidic Systems for Molecular Analysis
Sammanfattning : Improved methods are needed to interrogate the genome and the proteome. Methods with high selectivity, wide dynamic range, and excellent precision, capable of simultaneously analyzing many biomolecules are required to decipher cellular function. This thesis describes a molecular and microfluidic toolbox designed with those criteria in mind. LÄS MER
