Stable Aqueous Suspensions of Manganese Ferrite Clusters with Tunable Nanoscale Dimension and Composition

In this video, we present the synthesis, of super paramagnetic manganese ferrite nano clusters. We report a one pot hydrothermal synthesis of manganese ferrite clusters or MFCs that offers independent control over both primary nanocrystal and cluster dimension, as well as the iron to manganese ratio. Magnetic separation allows for rapid sample purification while service functionalization using a sulfonated polymer ensures that the materials are non-aggregating, even in biologically relevant aqueous solutions.

The resulting products are well positioned for applications in biotechnology and medicine. Wash and thoroughly dry all glassware to be used in the synthesis. The amount of water in the synthesis impacts the dimensions of the MFCs.
