1. Linear and Branched Chitosan Oligomers as Delivery Systems for pDNA and siRNA In Vitro and In Vivo
Sammanfattning : In this thesis, chitosan, a biocompatible polysaccharide that has been approved as a food additive was selected as a platform for the development of safe, efficient non-viral gene delivery systems to mammalian cells. Previously, chitosan-based gene formulations had been generally associated with high molecular weight chitosans, which were poorly characterised in terms of molecular weight distribution and degree of acetylation.

2. Electrochemical Methods for Drug Characterisation and Transdermal Delivery : Capillary Zone Electrophoresis, Conductometry, and Iontophoresis
Sammanfattning : 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.
