From the page: "Genetically engineered cells make their own nanomagnets, providing clear MRI images. "

Tracking gene expression in vivo with bacterial MagA DNA. Apparently the protein encoded by this gene is a Fe(II)/H+ transporter that will transport iron into a vesicle, making it accumulate. Pretty neat stuff.

The full article in MRM is here (only available for those with a subscription or institutional access).

From the page: "Using a gene from a magnetically sensitive bacterium, scientists have genetically engineered mammalian cells to produce magnetic nanoparticles. The finding, by a team of Emory University researchers, could give medical researchers a new way to more precisely track cells in the body. "
