Multicore assemblies potentiate magnetic properties of biomagnetic nanoparticles

Abstract

Highly potent magnetic nanomaterials are developed by encasing multiple magnetic cores inside a thin silica shell, in much the same way as the pomegranate fruit contains many seeds within a thin skin. This construct not only produces materials that are biocompatible but also ones that reach theoretically maximum transverse relaxivity. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
