1. Thermodynamics of Peptide Nucleic Acid Interactions with DNA
Abstract : Peptide Nucleic Acid (PNA) is a DNA mimic with the natural nucleobases attached to a charge-neutral pseudopeptide backbone. It has remarkably strong and sequence-specific binding affinity to natural nucleic acids (DNA and RNA), mainly attributed to the lack of charge in the PNA backbone. READ MORE

2. Intelligent Nucleic Acid Interactions with Peptide Nucleic Acid (PNA) and Recombination Enzyme RecA
Abstract : The work presented in this thesis focuses on interactions between nucleic-acids in biological systems, particularly interactions of the promising drug-candidate peptide nucleic acid (PNA), and on protein-DNA intermediates during recombination. Several experimental techniques, mainly circular dichroism and fluorescence spectroscopy, have been used to characterize the interactions of interest. READ MORE

4. A biophysical study of nucleic acid interactions with analogues and drugs
Abstract : work presented in this thesis concerns studies on the physicochemical nature of interactions between nucleic acids and small ligands. The outcome of such studies can yield insights at a molecular level into the physiological mechanisms of action of biologically active nucleic-acid binding molecules. READ MORE

5. Cell-penetrating peptides and bioactive cargoes : Strategies and mechanisms
Abstract : The cell membrane is an impermeable barrier for most macromolecules. Recently discovered cell-penetrating peptides (CPPs) have gained lot of attention because they can cross the membrane, and even more, carry cargoes with them. How CPPs enter cells is still not clear, while the delivery of different cargoes has been convincingly shown. READ MORE
