📄 Abstract

High-temperature hydrolysis of FeCl3 in the presence of a surfactant gives monodisperse superparamagnetic colloidal nanocrystal clusters (CNCs) of magnetite with tunable sizes (30–180 nm; see scheme). The combination of superparamagnetism, high magnetization, and high water dispersibility makes these CNCs ideal candidates for applications such as drug delivery and bioseparation.
