Nanodiamond-enhanced Magnetic Resonance Imaging.

Nanodiamonds hold great potential for diverse applications due to their biocompatibility, non-toxicity and versatile functionalization. Direct visualization of nanodiamonds by means of non-invasive imaging techniques would open new venues for labeling and tracking, offering unprecedented and unambiguous detection of labeled cells or nanodiamond-based drug carrier systems. The structural defects in diamonds, such as vacancies, can have paramagnetic properties and potentially act as contrast agents in magnetic resonance imaging (MRI). We report the smallest nanoscale diamond particles, detonation nanodiamonds, to effectively reduce longitudinal relaxation time T
