Diffusion MRI differs from conventional MRI in that it measures the mobility of water within tissues in addition to reflecting tumor size and shape. This technology gained its first clinical ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Between 1972 and now, this technique, termed fluorescence correlation spectroscopy (FCS), has been applied to measure the kinetics of chemical and biological reactions, diffusion and flow. The rates ...
