Explosif sous forme de poudre nano vu en microscopie à force atomique

An explosive in the form of nanopowder, observed using an atomic force microscope. With a view to obtaining the finest possible diamond nanoparticles, research scientists have developed a nanocrystallisation process by turning a microstructured charge (5-100 µm) into a nanostructured charge (50-200 nm). They then detonated this nanostructured charge in order to synthesise nanodiamonds whose size (1-3 nm) is suitable for use in various fields, such as medicine, cryptography, optical protection, etc. This result is a world first. Diamond nanoparticles could be used as vectors for medication in targeted treatments for cancer cells, for example.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
