Clothing

• Dust ?sweat ?sebum(??)and other
  secretion(???)may 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.

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
Towel extremely soft?good water
absorption?never color fading?easy wash?long
duration?good quality of decontamination.
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.

Food
Nanotechnology brings new foods to us
With nanotechnology , we can mash
cellulose(???) into monosaccharide(??)?glucose(???
) 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.

1?Body stealth special geometrical shape
to reduce the reflection of radar wave
absorbing paint-coat2?Engine stealth add
cooling mechanism to the gas vent in order to
reduce the leak of infrared.3?Electronic
stealth use 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.

There are still many applications of
nanotechnology in our life. We only collected
small part of them here, and since time is
limited we have to stop here now
