ASU Electronic Theses and Dissertations
This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.

The molecular complex formation in aqueous solution was studied by electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry. The formation of both 1:1 and 2:1 complexes between one or two reading molecules and a DNA nucleotide were observed by ESI mass. A series of amino acids and carbohydrates were also examined by mass spectrometry to show the formation of non-covalent complexes with imidazole reader in aqueous solution. The experimental results were compared by calculating energies of ground state conformers of individual molecules and their complexes using computer modeling study by DFT calculations. These studies give insights into the molecular interactions that happen in a nanogap during recognition tunneling experiments.
