1. Photochemical Surface Functionalization : Synthesis, Nanochemistry and Glycobiological Studies
Sammanfattning : This thesis mainly deals with the development of photochemical approaches to immobilize carbohydrates on surfaces for glycobiological studies. These approaches have been incorporated into a number of state-of-the-art nanobio-platforms, including carbohydrate microarrays, surface plasmon resonance (SPR), quartz crystal microbalance (QCM), atomic force microscopy (AFM), and glyconanomaterials.

2. Macromolecules at Interfaces
Sammanfattning : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). LÄS MER
3. Studies of Glycosaminoglycan Interactions - Surface Immobilization Strategies and Biosensing Applications
Sammanfattning : Many important biological functions of glycosaminoglycans (GAGs) have been highlighted in research literature during recent years. GAGs often serve as function-bearing structural elements in the extracellular matrix (ECM), but are also constituents of the cell membrane. GAGs take part in various biological mechanisms, e.g. LÄS MER
4. Biosensor surface chemistry for oriented protein immobilization and biochip patterning
Sammanfattning : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. LÄS MER
5. Enzyme immobilization in mesoporous silica
Sammanfattning : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. LÄS MER
