Introduction
One type of carbon nanomaterial, the so-called ultradispersed
detonation diamond (UDD), can be synthesized by detonation
of explosives in closed volumes under an inert atmosphere,
followed by subsequent chemical treatments of detonation carbon
soot to remove impurities and non-diamond forms of carbon
[1, 2]. UDD is an interesting object for investigations from many
point of view, such as the production methodology (utilization
of explosives), the nanostructure of the UDD particles (crystal
mean size is in the range 3-6 nm with narrow size distribution)
and the several novel technological applications of UDD [3, 4].
Current and potential applications of UDD cover wide fields
starting from lubricants, polishing pastes and galvanic coatings [3],
through polymer composites [5-7], sorbents [8-10] and catalysts
[11, 12] to biolabeling [13], drug delivery [14], medical tomography
[15] and implants [16] in biomedicine (see recent reviews in this
field [17-19]).
