The FeraSpin™ Series is a product family of six size-selected agents derived from FeraSpin R:
FeraSpin XS to FeraSpin XXL. The identical chemical composition and ultra-narrow size distribution of these fractions allow for fine-tuning of the pharmacologic profile according to your own innovative applications.

The unique series of size-selected superparamagnetic iron oxide (SPIO) nanoparticles:

  • Is analogous to human clinical agents
  • Encompasses particle fractions ranging from ultrasmall to large particle sizes
  • Offers tunable T1 and T2/T2* relaxation properties
  • The FeraSpin Series is Viscover's unique and powerful toolbox for nanoparticle MRI research

    • Apply the FeraSpin Series to

    • Adjust your unique MRI contrast agent for extended circulation, or macrophage and organ-specific uptake by the liver and spleen
    • Perform innovative in vitro and in vivo studies such as stem cell tracking, MR sequence development and Magnetic Particle Imaging (MPI)
