Diamond in nanosizes can be achieved by two methods:
1. Detonation nanodiamond
2. CVD growth (and here)
The robust nature of diamond makes its nano form attractive. As in the bulk form, nano diamond may enable mechanically stable structures and constructing mini devices, i.e. nano robots, would become more feasible and durable. Or simply, nanodiamonds can be used as vehicles for drugs into the harsh or selective environments within the living organisms.
New research on this matter was published -relatively- recently, having nanodiamonds clustering with doxorubicin hydrochloride (DOX) (an apoptosis-inducing drug that is used in chemotherapy) and carrying them into the infected living cells to cause the death of the cell.
NOTE: The picture -of course- is not a nano diamond, the real -not so pretty- nanodiamond can be seen here
