From AZNano:

Scientists from the University of Basel have developed nanoparticles that have the potential to serve as contrast agents for magnetic resonance imaging.

In comparison to the actual contrast agents, these new nanoparticles produce around ten times more contrast and are responsive to particular environments. The results have been published in the journal Chemical Communications.

Imaging tissues obtained through magnetic resonance imaging (MRI) is improved by contrast agents. The identification of structural details in the body is majorly enhanced by contrast agents, and the current substances develop insufficient contrast for the identification of diseases in its early stages.

The existing contrast agents are not capable of sensing their biochemical environments and this is considered to be another limitation. Researchers from the Department of Chemistry at the University of Basel have created nanoparticles capable of serving as “smart” contrast agents for MRI.
