1. Allergenic oxidation products in ethoxylated non-ionic surfactants : Chemical characterization and studies on allergenic activity
Abstract : The susceptibility of ethoxylated non-ionic surfactants to oxidation on exposure to air was investigated. Surfactants have a complex chemical composition and are widely used in a variety of applications for to their amphiphilic properties. Ethoxylated non-ionic surfactants are regarded by the producers to be stable at normal handling. READ MORE

4. Colloidal suspensions of mesostructured silica
Abstract : Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm. Since the silica most often is amorphous, the material lacks short range order but the pores may be arranged in different structures generating a long-range order. READ MORE

5. Micro-scale Platforms for Investigations of Biological Structures
Abstract : This thesis describes the development of innovative micro-scale platforms as a means to address the current challenges within the field of cell biology, and to provide an interface between miniaturized analytical technology and experimental systems for the life sciences. The work includes an analytical platform for rapid assessment of the viability of adherent single cells; a surface patterning strategy for investigations of cell-to-cell communication via protrusions; a versatile microfluidic probe in SU-8 hard-polymer, and a microfabricated millimeter-wave measurement system for the identification and characterization of niosome (non-ionic surfactant vesicle) constituents, which is operated in a label-free, non-invasive manner.
