"Organic Nanodiamonds"

We grow nanodiamonds directly from organic molecules without appreciable decomposition of the starting material. This opens the door to engineered growth of fluorescent nanodiamonds wherein a single diamond-like molecule can act as a seed for nanocrystal growth. By substituting atoms at particular locations in the seed molecule it will be possible to produce complex multi-atom color centers like the bright nickel/nitrogen (NE8) center, or even complete quantum registers, for example nuclear storage registers precisely coupled to optical-spin interfaces like the nitrogen-vacancy (NV) center. Other benefits to this approach include near-deterministic number and placement of color centers, so that nanodiamonds no matter how small can be designed to have at least one bright and photostable fluorescent emitter. Given the low-toxicity of diamond and the demonstrated small size (1.6 nm) for photostable fluorescent nanodiamonds this could lead to new generation of non-bleaching fluorescent bio-markers that are smaller than many existing dye molecules.
