The site-specific attachment of nanoparticles is of interest for biomaterials or biosensor applications. Polymer brushes can be used to regulate this adsorption, so the conditions for selective adsorption of phosphonate-functionalized nanoparticles onto micropatterned polymer brushes with different functional groups are optimized. By choosing the s...

It is important to understand the physicochemical mechanisms that are responsible for the morphological changes in the cell membrane in the presence of various stimuli such as osmotic pressure. Lipid rafts are believed to play a crucial role in various cellular processes. It is well established that Ctb (Cholera toxin B subunit) recognizes and bind...

The formation of fluorinated monolayers with a minimized surface energy and an improved chemical stability on specific substrates will enable outstanding tribological properties and is the main goal of the research described in this thesis. Inorganic substrates, such as Si(111), silicon carbide (SiC), chromium nitride (CrN), and organic nano-micro-...

This thesis aims at gaining fundamental insight on colloidal interactions in two types of apolar media, namely, liquid CO2 and (as a model for liquid CO2) n-hexane. The other components playing major roles are surfactants and water. The background of the work was to address the challenges met in the use of liquid CO2 as a dry-cleaning solvent, in p...

We present the results of atomistic simulations of metallic atomic-force-microscopy tips interacting with ionic substrates, with atomic resolution. Chromium and tungsten tips are used to image the NaCl(001) and MgO(001) surfaces. The interaction of the tips with the surface is simulated by using density-functional-theory calculations employing a mi...

Amyloid assemblies are associated with several debilitating human disorders. Understanding the intra- and extracellular assembly of normally soluble proteins and peptides into amyloid aggregates and how they disrupt normal cellular functions is therefore of paramount importance. In a recent report, we demonstrated a striking relationship between re...

Room temperature ionic liquids (ILs) are high performance fluids with a wide thermal stability range. In this work we present the first study of ILs as lubricants under a wide range of temperature conditions (−30, 100, and 200 °C). The tribological performance of the imidazolium ionic liquids 1-hexyl, 3-methyl (L106) and 1-octyl, 3-methyl (L108) im...

Currently, there is no satisfactory molecular theory allowing for the prediction of the interaction of two materials across their mutual interface. All existing theories assume there is a part of the molecular interactions involved that obeys the London inverse-sixth power law, as is valid for the separations encountered in gases. It is shown that,...
