Liquid state Dynamic Nuclear Polarization probe with Fabry-Perot resonator at 9.2Â T

► 9.2 T Dynamic Nuclear Polarization probe for liquid samples has been constructed. ► The probe based on the combination of the Fabry-Perot and stripline resonators can maintain up to 100 nl of aqueous samples. ► Improved NMR signal amplitudes promise in situ DNP applications on biomolecules.
