Methods for Studying Nucleic Acid/Drug Interactions

Meni Wanunu completed his Ph.D. in 2005 at the Weizmann Institute of Science, where he specialized in supramolecular chemistry, self-assembly, and nanomaterials science. He then carried out a postdoctoral position at Boston University and a research associate position at the University of Pennsylvania, where he developed ultrasensitive synthetic nanopores for nucleic acid analysis at the single-molecule level. Currently, he is an Assistant Professor at the Department of Physics and the Department of Chemistry and Chemical Biology at Northeastern University, Boston. His research interests include developing chemical approaches for investigating biomolecular structure and behavior, nucleic acid mechanics and dynamics, and probing biological processes at the single-molecule level. Yitzhak Tor carried out his doctorate work at the Weizmann Institute of Science, earning his Ph.D. in 1990. After a postdoctoral stay at the California Institute of Technology (1990–1993), he took his first faculty position at the University of Chicago. In 1994, he moved to the University of California, San Diego, where he is currently a Professor of Chemistry and Biochemistry and the Traylor Scholar in Organic Chemistry. His research interests are diverse and include chemistry and biology of nucleic acids, the discovery of novel antiviral and antibacterial agents, as well as the development of cellular delivery agents and fluorescent probes. He is currently the Editor in Chief of Perspectives in Medicinal Chemistry (http://la-press.com/journal.php?journal_id=25) and Organic Chemistry Insights (http://www.la-press.com/organic-chemistry-insights-journal-j104). Away from chemistry, his interests are predominantly in music, playing, recording and producing his own instrumental CDs.

"By focusing on a selection of novel and emerging techniques, Wanunu and Tor provide a remarkable overview of biophysical and computational advances in structure-based investigations of the interactions between nucleic acids and small-molecule ligands. An impressive collection of approaches is described: analytical biophysical techniques alongside novel exploitation of chemical and computational tools. Indeed, the smart combination of results obtained by classical methods with state of the art biophysical approaches reveals astonishing insights, thus paving new research avenues in this central area of research."—Prof. Ada Yonath, Weizmann Institute of Science, 2009 Nobel Laureate in Chemistry
