1. Macromolecules in microparticles : preparation, characteristics and applications
Sammanfattning : .... LÄS MER
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. Labelling of various macromolecules using positron emitting 76Br and 68Ga : Synthesis and characterisation
Sammanfattning : Different prosthetic groups containing a trialkylstannyl- and an electrophilic group have been synthesised and labelled with the accelerator produced 76Br (T1/2=16 h) through oxidative bromination. The labelled prosthetic groups were conjugated to amino-containing macromolecules such as proteins and 5´-modified oligonucleotides. LÄS MER
4. Ions interacting with macromolecules : NMR studies in solution
Sammanfattning : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. LÄS MER
5. Diffusion studies in gels using holographic laser interferometry
Sammanfattning : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.
