摘要：

The production of spherical monodisperse iron-oxide microparticles in the size range between 0.8 and 5 mum is described. The particles can be ferrimagnetic (Fe3O4) or non-magnetic (alpha -Fe2O3). The particles were radiolabeled with Te-99m or In-111, and the leakage of the radiolabel within 24 h was 0.1% in the human lung. The particles can be used to study the motility and the integrity of living cells. (C) 2001 Elsevier Science B.V. All rights reserved.
