Our aim is to produce the smallest diamonds
in the world!
NANODIAM = nanodiamonds
in form of layers or powders
They are so small that it's possible to
see them only by Atomic Force
Microscope.
Very thin layer consists of tiny
crystals of diamond, so tiny that one
diamond crystal is of the size of
nanometers, one millionth of a
millimeter 2

Glioblastoma multiforme Glioblastoma multiforme cells were cultured on the
chorioallantoic membrane of chicken embryo and after 7 days of incubation, were treated with carbon nanoparticles administered in ovo to the tumor. Diamond nanoparticles significantly decreased tumor mass and volume and vessel area. Quantitative real-time polymerase chain reaction analysis showed downregulated fibroblast growth factor-2 and vascular endothelial growth factor expression at the messenger ribonucleic acid level. The present results demonstrate antiangiogenic activity of carbon nanoparticles, making them potential factors for anticancer therapy.

Few grams of nanospider has the same surface area as of the football field….
Ideas:
• Sponge made from nanospider and modificated
ND inclusions as a containar for hydrogen
• Sponge made from nanospider and modificated
ND inclusion as a source of ions (with very
extended surface)
• After information about application of
detonation ND as solid lubricant - additive for
engine oil – we carry out research in this area.

Bioactivity of diamond
The most important is the bioactivity of diamond powder in human organism.
This mechanism is based on the influence of diamond on membrane cell and DNA in nucleus.
Diamond Powder is a potential medicine because in examinations in vitro and in clinical research has antioxidant, antiinflammatory, anticancerogenic and antiallergic prpperties.
