Microdiamonds

Caption

The microdiamonds used as biological tracers are about 200 microns across, less than one-hundredth of an inch. They fluoresce red but can also be hyperpolarized, allowing them to be detected both optically -- by fluorescence microscopy -- and by radio-frequency NMR imaging, boosting the power of both techniques.
