Highly Water‐Dispersible Biocompatible Magnetite Particles with Low Cytotoxicity Stabilized by Citrate Groups

Uniform magnetite particles stabilized by citrate groups were successfully synthesized by a modified high-temperature solvothermal reaction. Cell imaging reveals that the water-dispersible particles can readily penetrate into cells without destroying them, indicating an excellent biocompatibility. A high enrichment capacity of the magnetite particles for separation of trace peptides is observed. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
