1. Groove-binding Unsymmetrical Cyanine Dyes for DNA Applications
Sammanfattning : This work focuses on interactions between DNA and a group of newly developed unsymmetrical cyanine dyes. The aim of the work was to discover fluorescent dyes that can be used in biophysical studies of natural DNA where minimum perturbation of the DNA-helix is essential, where a slow dissociation rate of the dyes is needed and where the ionic strength is an important parameter.

2. Detection of Biomolecules: Syntheses and Studies of Minor Groove Binding Unsymmetrical Cyanine Dyes and Chromogenic Enzyme Substrates
Sammanfattning : Visualisation or detection of biomolecules is usually achieved by the use of fluorescent or highly coloured chromophores. The work presented in this thesis deals with the development of new chromogenic substrates for the detection of enzyme activity, and new DNA-binding fluorescent dyes for staining of DNA. LÄS MER

4. DNA-Photosensitization by New Drugs for Photoinactivation of Viruses and Phototherapy of Tumors
Sammanfattning : Cyanines and pyropheophorbides are two classes of photoactivable dyes which are particularly interesting for photosterilization of blood used in transfusion and for treatment of localised cancers by photodynamic therapy (PDT). After a bibliographic review about the principal mechanisms of DNA photosensitization, studies about the photosensitizing properties of these two families of compounds are presented. LÄS MER
