  • 3D, More*


What are Nanodiamonds?

Nanodiamonds are carbon nanoparticles with diamond cubic lattice core and hybrid graphene-like or amorphous carbon surface structure, possessing diamond’s extreme physical, mechanical, chemical, electrical and optical properties. Nanodiamonds chemically-active multi-faceted surface provides robust versatile compound delivery-systems for a wide range of applications.

        Nanodiamonds scale

A nanometer (nm) is one-billionth of a meter. The majority of nanodiamonds are sized ≈4-6 nm, have extremely high surface area to volume ratio (≈300-500 m²/g, about the surface size of a basketball court per 1 gram), with varied tunable surface functional groups and high adsorption capacity.


  • A human hair is approximately 90,000 nm wide

  • A sheet of paper is about 100,000 nm thick

  • There are 25,400,000 nm in one inch
