WHATISTHENANOTECHNOLOGY?
1 nanometer = 1 x 10-9m
Nanotechnology is the
understanding and control of
matter at dimensions of
roughly 1 to 100nanometers, where unique
phenomens enable novel
applications.

SMALL, BUTHOWSMALL?
Nanomaterials have sizes ranging between 0.1
and 100 nanometers. This size is hard to imagine.
For comparation , a DNA molecule is 2 nanometers
in diameter, the atoms are between 0.1 and 0.2nanometers, and a red blood cell is 7,000
nanometers in diameter.

BUCKYBALLS
they are 6 times lighter and
100 times more resistant
than the best steel
the agglomeration of these
balls result fiber that can be
placed in various materialsand the materials become
incredibly strong.

ARMORFOR"ROBOCOP" SOLDIERS
in 2020 all American soldiers
will be dressed in nanobut armor
the armor will defend them from
any devastating effects of bullets
and explosions

MILITARYWEAPON
soon we will see a gun with 4
pipes and laser guidance system
the most spectaculos thing is
that it uses several types of
ammunition

NANODOCTORSIN30YEARS
It will be very simple to use:we swallow a very
small doctor that can travel through the blood to every
sick cell and that's all.
The doctor will be good at all:
-to provide medication
-to remove tumors
-to do analysis and-to rebuild damaged tissue

NANOTECHNOLOGY IN COSMETICS
The specialists have developed a cream that
stimulates the skin and produce rejuvenation effects.
The principle is based on stimulation of the skin waterand effects obtained were visible .

ECOWASHINGBALLWHICHCANCLEAN
CLOTHESWITHOUTDETERGENT.
Is a natural way of cleaning
clothes that are protected against
oxidation so that keeps the intensity
of colors and the fibers not lose theflexibility.
In addition, the clothes will get
a fresh scent because the balleliminate mold, pathogenic
organisms and any unpleasant
odors.

ARTIFICIALBLOOD
It is not as difficult as it seems:
hemoglobin extracted from marine
worms is the raw material forblood.
Nevertheless the process is
still slow and not enough demandworld
