    Particle Works' iron oxide coated cobalt particles are engineered to maximize magnetic performance. The particles comprise of a monodisperse cobalt core (typical CV values <6%) and a magnetite shell of 2 nm thickness.
    The size of the cobalt core is 8 nm this corresponds to a single magnetic domain limit for cobalt and ensures strong magnetic performance of the material. The core-shell arrangement protects the cobalt cores from oxidation and enables our customers to take advantage of Fe3O4 surface chemistry which is often familiar from their previous work.

    Typical applications and benefits include:
    Magnetic separation - Ability to use Co in oxygen environments.
    Targeted drug delivery - Enhanced drug delivery efficiency.
    Magneto-thermal heating - Enhanced specific power loss densities in magneto-thermal heating.
    Magnetic lateral flow assays - Faster more reliable results in lateral flow tests.

  • Particle Works designs and fabricates a wide range of metal nanoparticles, quantum dots and hydrogels with tight control of critical parameters such as particle size, shape and architecture and supplies them with comprehensive characterization data. These standard products are designed to maximize material performance – including catalytic activity, magnetic strength and optical resonance – helping to standardize processes and accelerate development across a wide range of disciplines. The Particle Works team can also provide customer-specific services to simplify and accelerate proof of principle, materials optimization and scale-up studies.
