Seed-mediated growth of ultra-thin triangular magnetite nanoplates

Abstract

We report a simple strategy for the growth of ultra-thin magnetite nanoplates. The injection of a large portion of precursor after stunted nucleation is favorable for both the survival of metastable structures in seeds and their subsequent development into anisotropic nanoparticles. The as-synthesized ultrathin triangular magnetite nanoplates are expected to have important applications as T₁ contrast agents for magnetic resonance imaging.
