Kinetically Controlled Morphologies of Magnetic Nanoparticles through Ligand and Precursor Chemistry.

ABSTRACT: Kinetically controlled morphologies of colloidal magnetic nanoparticles possess unique magnetic properties, making them highly promising for applications in magnetogenetics as magnetic torque probes. Yet, their size-controlled chemical synthesis is in its nascent state. Here, we present a capping-ligand-directed approach to tune the morphology and magnetic properties of Co _x Zn _y Fe_3‑(x+y)O₄ nanoparticles by adding sodium oleate as a cocapping ligand to oleic acid during synthesis, resulting in the formation of monodisperse tetrahedral nanoparticles. Increasing the molar ratio of sodium oleate to oleic acid promotes facet-selective passivation along {111} facets, leading to progressive truncation of tetrahedra and yiel
