Diamond is the hardest known material. The industrial production of nano-scaled diamonds takes place at high temperatures and under high pressure. Applications of diamond nanoparticles include their use as filling components in synthetic materials and in the production of polishes. In oil for bicycle chains they supposedly reduce the friction. Diamond electrodes are also used in industrial wastewater treatment facilities for water purification purposes.


How can I come into contact with this material?

In the medical field, diamond nanoparticles are tested as carrier molecules for targeted drug delivery in the human body.


Is there any risk from this material to humans and the environment?

Diamond nanoparticles are considered to be non-toxic. The nanoparticles were proven to be well-tolerated by the human body and thus future medical applications of nano diamond can be anticipated. Experiments in the laboratory have shown that the uptake of diamond nanoparticles by animals did not cause any observable negative effects. In addition, there were no detectable adverse effects on the lungs after the inhalation of diamond nanoparticles. Diamonds are naturally occurring materials and so far, no artificially produced diamond nanoparticles have been detected in the environment.



In everyday life the human body and the environment are only exposed to small quantities of diamond nanoparticles and diamond is considered to be non-toxic.


By the way...

  • Naturally occurring diamonds are used as gemstones in jewellery manufacturing.
  • The surfaces of diamond nanoparticles can be coated with a variety of compounds including drugs for medicinal purposes.
