Novel Spectroscopic Tools To Differentiate Molecule-Dna Binding Interactions, Sense Dna And Track Dna Melting, Saad Hmoud Alotaibi

Dissertations

The discovery of DNA as a genetic material and its double helical structure led to numerous studies directed at understanding molecule-DNA interactions. These studies have played an integral role in medical diagnostics, forensics, imaging and therapeutics. Typically, molecule-DNA interactions have two prominent modes: intercalation and minor groove binding. Several optical techniques are available that can monitor molecule-DNA binding interactions, but they cannot differentiate between intercalation and minor-groove binding. The major goals of the research are to develop novel optical spectroscopic tools that can differentiate molecule-DNA binding interactions, selectively and sensitively detect one form of DNA over another, and track DNA …
