Latest Patents

Qi Chen's latest patents focus on a scalable process for manufacturing iron cobalt nanoparticles. This process involves producing CoFe nanoparticles, where x is an integer from 20 to 95. The method includes providing a first aqueous hydroxide solution, preparing a second aqueous solution containing iron ions and cobalt ions, and depositing measured volumes of the second solution into the first. This coprecipitation occurs in an essentially oxygen-free environment. The nanoparticles are then annealed at ambient temperatures to achieve soft nanoparticles with targeted particle size, saturation magnetization, and coercivity. The CoFe magnetic nanoparticles exhibit a magnetic moment of 200-235 emu/g, coercivity of 18 to 36 Oe, and a size range of 5-40 nm. These high magnetic moment CoFe nanoparticles have potential applications in drug delivery, magnetic resonance imaging, magnetic immunoassays, magnetic labeling, wastewater treatment, and magnetic separation.
