Abstract

original image

Konjugierter „Agent“: Ein GdIII-angereichertes DNA-Goldnanopartikel-Konjugat für die intrazelluläre Kernspintomographie und Fluoreszenzbildgebung wird vorgestellt. Das Reagens zeigt hohe Relaxivitäten pro Partikel und gutes Zellaufnahmevermögen, wodurch die Bildgebung kleiner Zellpopulationen möglich wird.
