Clothing
Dust, sweat and other secretionmay stick to our
clothes .These sewage may cause the development
of different kinds of microbes which will give
off bad smell and finally lead to dermatitis and
other skin diseases. If we add antibacterial
agent (produced by nanotechnology) into the dye,
the antibacterial agent sticking to the clothes
will play its role, then antibacterial clothes
are made.

How does it work?Lets see

Clothing
There are two methods widely used
1.Destroy the structure of bacterial or virus
protein . Usually precious metals such as silver
can do this by exchange of molecules. Since
nano-materials are very small , they can
diffuse easily and act efficiently so they can
used as antibiotic.
2.Use photoelectric material. For example, TiO2
can produce holes and electronics when activated
by light with specific wavelength, this will lead
to ionization of protein tissue and achieves
the sterilizing effect.

Clothing
Thermal underwear Some nanoparticles have
strong ability of absorbing infrared ray from our
body. So we can add these particles into clothing
fibers to improve the ability of keeping warm of
our clothes.
Towel extremely soft, good water absorption,
never color fading, easy wash, long duration,
good quality of decontamination.

Food
Nanotechnology brings new foods to us
With nanotechnology, we can mash cellulose
into monosaccharide, glucos and cellobiose, thus
many organics can be used as nutritive
substance. With nanotechnology, we can manipulate
some nucleotides in DNA or even rearrange
several atoms to produce new genetic foods.

Housing
New decorated houses are filled with harmful gas
such as formaldehyde or methylbenzene. some of
them are blastomogens. While nanomaterials can
degradation those harmful gas in the air,such as
nano-TiO2, it has high degradation rate and it
can turn those harmful gas into CO2, H2O and
organic acid.

Housing
Traditional paint cant maintain for a long
time and can not be washed too often . While
newly produced paint with nanotechnology has
good qualities . The painted wall can be washed
for ten thousand times or even more which has
improved by ten times. Glass and ceramic
tile painted with nano-coating can be
self-cleaning. With nano-materials catalysis ,
any particles sticking to the glass or ceramic
tile including greasy dirt and bacterial will
turn into gases or something that can be wiped
easily under the sunshine.

Housing
Use nano-silver composite to produce the cavity
of washing machine can enhance the tenacity
prolong the duration and improve the resistance
of washing machine. And it also has the ability
of self-cleaning.

Like pallet, rack, drawer, doorknob which might
touch our body or foods were made from materials
comprising of nano-antibacterial material. Thus
it could prevent bacterium from staying in the
refrigerator.

mechanism to the gas vent in order to reduce
the leak of infrared.3.Electronic stealthuse
passive radar instead of active radar and
communication apparatus to keep electronic
silence.
Tranportation
Stealth aircraft can not be detected easily by
radar

• Reasons
• nano-particles are far smaller than that
  of the infrared and radars wavelength.
  Supersonic wave can pass through them with
  little or even no reflection.
• Nano-particles have high specific surface, they
  can absorb infrared and electromagnetic wave
  very efficiently so infrared detector or radar
  receiver could just receive little reflective
  wave.
