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