Fluorescent nanodiamonds successfully injected into living cells

As odd as it sounds, many scientists have attempted to place extremely small diamonds inside living cells. Why? Because nanodiamonds are consistently bright and can give us unique knowledge about the inner life of cells over a long time. Now physics researchers have succeeded in injecting a large number of nanodiamonds directly to the cell interior.
