• Fluorescent Nanodiamonds (FNDs) are Nano scale diamond particles composed of carbon atoms, exhibiting stable fluorescence properties. 
  • Unlike traditional fluorophores, they are highly resistant to photobleaching and photoblinking, making them ideal for long-term imaging and sensing applications.

Key Properties of FNDs

  • Fluorescence Mechanism: 
  • FNDs emit light at a lower frequency when exposed to high-frequency radiation, a property known as fluorescence. 
  • This is due to nitrogen-vacancy (NV) centres and other defects within the diamond structure.
  • Photostability: 
  • Unlike organic dyes or quantum dots, FNDs do not degrade under prolonged exposure to light.
  • Biocompatibility: 
  • FNDs are non-toxic and chemically stable, making them suitable for biomedical applications.
  • High Chemical and Thermal Stability: 
  • Their structure remains intact under extreme conditions, including high temperatures and harsh chemical environments.
