1. Unveiling biomacromolecule interactions-NMR and optical spectroscopy studies on ligand binding to DNA and lysozyme
Sammanfattning : Studies on intercalation of bulky binuclear ruthenium compounds into DNA have attracted attention due to their slow dissociation rate and sequence selectivity. Previous results showed that dumb-bell shaped molecules of the type [μ-(bidppz)(L)4Ru2]4+, L=phenanthroline or bipyridine, bind rapidly on the surface of DNA prior to intercalation. LÄS MER
2. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State
Sammanfattning : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.

3. Molecular Recognition Mechanisms: Thermodynamics and Polarization Spectroscopy of DNA--Intercalator Complexes
Sammanfattning : Mechanisms for molecular recognition in DNA--intercalator complexes have been investigated by optical spectroscopy. The effect of electrical charge on binding geometry and binding thermodynamics was studied using 2,7-diazapyrene (DAP) and its N-methylated cations DAP+ and DAP2+ as model ligands. LÄS MER
4. 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
5. Studies of carbon nanomaterials based on fullerenes and carbon nanotubes
Sammanfattning : Materials based on fullerenes and carbon nanotubes are very much different from most “traditional” materials, primarily because they are built from nanosized molecules with highly symmetry-dependent properties. Being the subject of a very active research field over the last twenty years, carbon nanostructures proved to be indeed extraordinary. LÄS MER
