What is dynamic nuclear polarization?
Dynamic nuclear polarization (DNP) is a technique that enhances the sensitivity of NMR by polarizing the nuclei of atoms in a sample.
How does DNP improve NMR sensitivity?
DNP increases the polarization of nuclear spins, leading to stronger NMR signals and improved detection of metabolic processes.
What are the applications of DNP in neuroscience?
DNP can be used to study metabolic processes in real time, providing insights into enzymatic reactions in biological systems.
Who contributed to the installation of the DNP equipment?
The installation involved collaboration among the NMR team, including Gildas Bertho and Fatiha Kateb.
What is the significance of real-time monitoring in enzymatic studies?
