One‐Pot Synthesis of Highly Magnetically Sensitive Nanochains Coated with a Highly Cross‐Linked and Biocompatible Polymer

Abstract

Neptune's necklace: Fe3O4 colloidal nanocrystal clusters (ca. 200 nm in diameter) were organized into one-dimensional nanochains and coated with a highly cross-linked polymer in a facile one-pot synthesis (see picture). The nanochains have enhanced hydrogen T2 relaxation rates, facile magnetic manipulation, good water dispersivity, and excellent biocompatibility.
