Micro-engineered local field control for high-sensitivity multispectral MRI : Article : Nature
the physics in the paper are kind of scary, but the idea is pretty cool — orthogonal “filter wheels” for MRI (by chemical shift — does that really work?) that let you tag different cell substituents the way you can use differently “colored” fluorescent antibodies to tag multiple proteins at once, and then view them through filters to separate the signals.
