Figure 3. Fluorescence imaging of 90 nm nanodiamond in monocyte-derived macrophages.

The nanodiamonds were suspended in the growth medium before uptake by the macrophages. a), b) large field of view encompassing multiple macrophages in both wide-field fluorescence and super-resolution radial fluctuations (SRRF) imaging modes. c), d) detail view of single macrophage in both widefield and SRRF modes.
