What is it about?

An important approach to improve the resolution in non-invasive medical diagnosis techniques is to utilize nanoscale materials which improve tissue contrast. We have discovered that laboratory grown ferrimagnetic cluster-like colloidal entities, composed of nanocrystals of the oxidized form of naturally occurring magnetite (loadstone), exhibit a remarkable four-times better generation of contrast enhancement compared to commercially available products utilized in MR imaging methods.

Why is it important?

This work unveils the directed assembly of inorganic nanocrystals as an avenue to impart a collective nature in application-specific physical properties, which in the present case, offer the possibility for magnetically-driven image-guided diagnosis and therapy.
