Nanocrystalline diamond (NCD) films may be used in biosensing after modification of their surfaces with active functional groups. Here, surface functionalization of O‐ and H‐NCD films with amine groups was made by 2 plasma‐based processes: a) RF plasma treatment in ammonia, b) the deposition of thin amine‐containing plasma polymer via RF magnetron sputtering of nylon target in Ar/N 2 mixture. Amination of the NCD films by plasma treatment in NH 3 caused an attachment of 1% of primary amines but destroyed the surface conductivity of H‐NCD films. The 5% concentration of NH 2 was detected on the NCD covered with the plasma polymer. Moreover, the surface conductivity of H‐NCD films reached 10 −7 S.
