General description

The particle size of diamond nanopowder is less than 50 nm and surface area is an average of 100 m2/g. Diamond nanopowder may be produced by multicathode direct current plasma chemical vapor deposition and high pressure high temperature (HPHT). Potential uses of nano-diamond are in biosensor applications. Surface modification of nano-diamond may enhance its linking mechanism with specific biomolecules.
