16. Interaction Between Microgels and Oppositely Charged Proteins
Abstract : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.

17. Nano-segregated soft materials observed by NMR spectroscopy
Abstract : This thesis is about using nuclear magnetic resonance (NMR) spectroscopy for studying soft materials. Soft materials may be encountered everyday by most readers of this thesis, for example when taking a shower or watching TV. The usefulness of these materials originates from them being soft yet, at the same time, having some kind of a structure. READ MORE

18. Molecular Exchange in Colloidal Dispersions
Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

19. Cellulose nanofibril materials with controlled structure : the influence of colloidal interactions
Abstract : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. READ MORE

20. Charged Polymers: From DNA to Polyampholytes
Abstract : Three main themes are outlined in this thesis: Polyelectrolytes/DNA : In a living cell, DNA molecules have a compact conformation in order to fit in, while in a test tube they will take on an expanded cylindrical shape, due to the negative phosphate groups along the DNA molecule. With the help of computer simulations it has been shown that like-charged monomers of a poly- electrolyte can attract each other if the counterions are taken into account. READ MORE
