Superparamagnetic Iron Oxide Nanoparticles (SPIONS)

PrecisionMRX® SPIONS: Precisely engineered for superior magnetic relaxivity and biomedical applications.

How it Works

PrecisionMRX® nanoparticles are extensively characterized by small angle X-ray scattering (SAX) and transmission electron microscopy (TEM) to ensure the nanoparticle cores have a uniformly spherical morphology and are consistent in size with narrow dispersity, resulting in minimum batch-to-batch variability.

Particles from other suppliers typically have poor control over size and shape, making them less reliable and consistent for the demands of many applications.


High Magnetic Susceptibility

PrecisionMRX® nanoparticles have been developed for magnetic relaxometry and other demanding biomedical applications where the magnet susceptibilityof the nanoparticle can be instrumental.

The saturation magnetization of PrecisionMRX® nanoparticles is typically twice as great as conventional iron oxide particles, even in an applied low or weak magnetic field.


PrecisionMRX® nanoparticles can provide excellent contrast even at 1.5T


By using different MRI sequences, clear information anatomy (T1-weighted), nanoparticle location (T2-weighted) and magnetic susceptibility (T2*) can be achieved.


Lot-to-Lot Consistency

Our thermal decomposition manufacturing process allows precise control over size, shape, and magnetic properties of PrecisionMRX® nanoparticles. The manufacturing process is robust and produces high-quality magnetite core nanoparticles with minimal batch-to-batch variability, as seen here in nanoparticle images from three different batches:
