Abstract

(Chemical Equation Presented) High-temperature hydrolysis of FeCl 3 in the presence of a surfactant gives mono-disperse 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.
