Aktive Blockierung: Mit deuterierten Blockierungsreagentien werden oberflächenverstärkte DNP-NMR-Signale, die durch Methylgruppen enthaltende Substrate beeinträchtigt werden, wiederhergestellt; die Schutzgruppenfunktion auf der Oberfläche bleibt dabei erhalten (siehe Bild; DNP=dynamische Kernpolarisation). Unpolare Gruppen wie [D9]-Trimethylsiloxy (TMS) halten Radikale (gelb) von der Oberfläche fern und vermindern dadurch schädliche paramagnetische Effekte.
