Kaminker, I., R. Barnes, and S. Han, Chapter Sixteen – Overhauser Dynamic Nuclear Polarization Studies on Local Water Dynamics, in Methods in Enzymology, Z.Q. Peter and W. Kurt, Editors. 2015, Academic Press. p. 457-483.
Abstract Overhauser dynamic nuclear polarization (ODNP) is an emerging technique for quantifying translational water dynamics in the vicinity (1 nm) of stable radicals that can be chemically attached to macromolecules of interest. This has led to many in-depth and enlightening studies of hydration water of biomolecules, revolving around the role of solvent dynamics in the structure and function of proteins, nucleic acids, and lipid bilayer membranes. Still to date, a complete and fully automated ODNP instrument is not commercialized. The purpose of this chapter is to share the technical know-how of the hardware, theory, measurement, and data analysis method needed to successfully utilize and disseminate the ODNP technique.
