NS3E is the only laboratory in Europe that prepares nanodiamonds by detonation. During the detonation of an explosive charge made of TNT and RDX, the residual carbon formed is converted to diamond particles.

The laboratory carries out unique studies on the doping and the surface chemistry of nanodiamonds. In addition, we are able to produce very small "ultimate size" nanodiamonds.

Applications of nanodiamond

- Hardening of composite materials
- Pressure-sensitive paints with fast reaction times
- Optical limitation
- Biomedical applications due to the excellent biocompatibility. Surface modifications allow the attachment of medicament molecules and the use as a drug delivery vector.
- Artificial retinas and other elements with a high added value.
