The absolute mag™ lanthanide-based magnetic particles, a type of super-paramagnetic particles formed through the reaction of lanthanide elements with massart magnetite under high-power ultrasonic irradiation. These particles have a γ-fe2o3 core, are positively charged, hydrophilic, and resistant to aggregation due to electrostatic repulsion. The lanthanide elements' +3 valence allows for further functionalization.

Lanthanide-Based Magnetic Particles The Absolute Mag™ Lanthanide-Based Magnetic Particles is a kind of super-paramagnetic magnetic particles formed by the reaction of a strong lanthanide element (Ln) mono-electronic oxidant with Massart magnetite under high-power ultrasonic irradiation. These particles have a γ- Fe 2 O 3 core and are positively charged, hydrophilic, and not easy to aggregate in aqueous suspensions/ferrofluids due to electrostatic repulsion. Since the lanthanide elements have a characteristic oxidation state of + valence, it is readily reacts with the Lewis base, therefore, the particles can also be further functionalization.
