Abstract

We show how the (29)Si NMR signals of dispersed inorganic nanoparticles of laponite® can be enhanced by Dynamic Nuclear Polarization (DNP). The direct DNP enhances the signals of (29)Si nuclei near unpaired electrons, whereas the indirect DNP via (1)H enhances the signals of more remote sites.
