1. Electrochemical Methods for Drug Characterisation and Transdermal Delivery : Capillary Zone Electrophoresis, Conductometry, and Iontophoresis
Abstract : This thesis concerns the development and utilisation of techniques for characterisation and transdermal delivery of various systems for pharmaceutical applications.The degree of dissociation of drug molecules and the mobilities of the different species formed are essential factors affecting the rate of drug delivery by iontophoresis.

2. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces
Abstract : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. READ MORE

3. Isotopes as Mechanism Spies : Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects
Abstract : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

4. Liquid Sensing : Development and Characterisation of an Electronic Tongue Based on Electrochemical Methods
Abstract : A new sensor technology for liquid sensing is reported, i.e. the electronic tongue based on electrochemical methods. Such a system involves the combination of non-selective sensors (metal electrodes) and a signal processing part. READ MORE

5. Release and transport of drugs in some complex and interacting systems
Abstract : Drug formulations come in many forms, some intended for direct and immediate action and others aiming at a controlled manner of drug delivery. Viewed in a more general way drug transport often involves charged units, it takes place in a medium which in many respects must be considered complex - to some degree even reactive. READ MORE
