Nanodiamanterna

Nanodiamanterna is a hypothetical class of nanoscale carbon-based materials described primarily in speculative nanoscience literature and science fiction. The term envisions particles that combine a diamond-like core with configurable interior features and surface chemistry to produce emergent optical and quantum properties. It is a coined concept rather than a material with established experimental realization, and descriptions vary across sources.

In proposed models, a Nanodiamanterna particle consists of a sp3-bonded carbon core in the range of a few nanometers to several tens of nanometers, surrounded by a functionalized shell. The interior may host defect centers or dopants intended to give defined photoluminescent or spin properties, while the outer shell provides chemical stability and bioconjugation capability. Some variants imagines a porous or layered interior to enable coupling between centers.

Synthesis and challenges: As a hypothetical construct, proposed routes frequently mention advanced synthesis techniques such as controlled chemical vapor deposition (CVD) to grow diamond-like cores or assembly of pre-made nanodiamond particles with engineered shell layers. Realizing precise interior defects, maintaining crystallinity, preventing aggregation, and achieving scalable production are cited as major obstacles.

Applications and research status: In speculative accounts, Nanodiamanterna could serve as a platform for quantum sensing, high-contrast bioimaging, drug delivery, and photonic devices due to its assumed combination of stability, optical addressability, and surface functionality. There is no widely accepted experimental demonstration in peer-reviewed literature to date, and the concept remains primarily in theoretical discussions and fiction. Research in related real materials, such as nanodiamonds with color centers, informs these ideas.
