Abstract: Des suspensions stables de particules magnétiques enrobées, préférablement de particules bioactives pouvant être remises en suspension et particulièrement utiles en imagerie à résonnance magnétique, sont produites par rupture de ce qu'on pense être des agglomérats cristallins d'un matériau de départ voisin, à particules magnétiques, en présence d'un matériau d'enrobage tel que cet enrobage se produise au cours de la rupture. Les particules sont généralement enrobées en suspension produisant ainsi une suspension stable de particules subdivisées. En choisissant avec discernement le matériau d'enrobage, préférablement une protéine ou un autre polymère actif au niveau biochimique ou biologique comme un anticorps, on obtient un produit bioactif pouvant être remis en suspension (colloïdal).
