The field of diamond research has been experiencing a rapid progress over the last two decades due to discoveries of chemical vapor deposition (CVD) method for synthesis of polycrystalline diamond thin films and industrial process for producing ultrananocrystalline diamond powder (with 2-20 nm particle size) by detonation of explosives. It was found that besides extreme mechanical and thermophysical properties, the synthetic diamonds also possess unique chemical and photophysical properties such as ability for surface functionalization and, in the case of detonation nanodiamonds, intrinsic bright fluorescence. The chemically surface-modified nanodiamonds are expected to combine the physical properties of diamond crystals and chemical properties of organic functional groups attached to their surface. Functionalization by specific organic groups and biomolecules can improve solubility in common solvents and water, and dispersion in polymers for nanocomposite processing. The tiny detonation diamond nanoparticles are expected to penetrate even the cell nucleus as passive transport into the nucleus is limited to particles of 9 nm or less in diameter. Functionalized fluorescent diamond nanoparticles present an opportunity for cell imaging with relatively little thermal or biochemical perturbations due to the optical transparency and biologically inert nature of diamond. These and other high expectations for application in engineering and biomedical fields continue to drive the current diamond research into a “new diamond age”.
