What is nanotechnology?
Nanotechnology is the engineering of functional systems at a molecular level.
Where nanotechnology means "build" something of a low level (nano) leading to a higher level.
Nano technology to adapt the formation of cell organism.
Tues join and work together into a collection of cells (tissue)>>> collection of work into organ tissue.>>> Set of organs into organ systems work together>>> collection of organ systems that work became an organism.
So from a collection of material on everything from the size of a nano eventually become an "artificial organisms" that have certain characteristics.
How big is a nano?
smaller size of the nano is angstrom. 1 angstrom = 1 / 10 nano meter (nm).
while the nucleus of atoms = 0.00001 nm
d all the existing universe is made of the atomic arrangement. And nature has had a perfect science to incorporate them.
For example, our bodies consist of millions of living cells are arranged in specific.
Here the cell is a natural nanomachine (natural nano-machines).
The size of atoms, atom has basic properties respectively. If we incorporate them in the nano size, then we arrange the atoms can be whatever we want. Size nano (nano scale) is the first point where we can put together a case, not from the size of atoms (atomic scale).
So how can we see these nano particles?
Nano technology, scientists must use scanning tunneling microscopes and atomic force microscopes to observe the material in nano size.
Scanning tunneling microscopes using weak electric current to scan the material. Atomic force microscopes to scan the surface with the tip of a very precise. Both microscopes send data to a computer, which will integrate information and depicted graphically to the monitor.
At this time, scientists have found 2 kinds of nanostructures.
1. nano-wires (wire diameter size 1 nm)>> in use to create tiny transistors on computer chips.
2. carbon nanotubes (cylinders of carbon atoms in nano-size.), where its use is now more popular in the appeal nano wires.
sheet of carbon atoms in hexagonal described. If we roll it, it will become carbon nano tubes (carbon nanotubes). Carbon nanotubes have different strengths, depending on the pattern roll.
With the proper preparation of the carbon atom, we can create carbon nanotubes that power hundreds of times stronger than steel, but six times lighter. This can be d utilized for the manufacture of cars and planes.
The result of nano technology that is already on the market:
1. Sunscreen
These glasses containing nanoparticles (nano particles) of zinc oxide or titanium oxide. The greater the nano particles of zinc oxide, it will leave white marks d faces. However, with small particle size will not leave white marks.
2. Self-cleaning glass
with nano-particles that give the effect of photocatalytic and hydrophilic on the glass. Photocatalytic = when UV light shining on the glass, this light will provide energy for the nanoparticles to break down (release) of organic molecules on the glass (dirt). hydrophilic = when water on the glass, the nanoparticles d spreading water all over the glass, so that automatically clean the glass.
3. Scratch-resistant coatings
with the addition of aluminum silicate nanoparticles, then make the car as well as a scratch-resistant glasses.
4. Antimicrobial bandages
bandages that use nanoparticles of silver. respiratory resist silver ion cell microbe, which allows the wound heal faster.
5. In 2002, the company Babolat, tennis racket manufacturers, using nano particles that cause light racket but stronger than steel. Tennis ball manufacturers are also using nano particles as a coating to prevent the air out of the ball. So the tennis ball is more durable, not easily deflated.
The Future of Nano technology.
with the development anoscopic machines, which called assemblers, scientists can program and manipulate the atoms in accordance with the antecedent desire.
a single nanoscopic machines require millions of years to assemble a useful material. To be more rapid d need millions of nanoscopic machines (assemblers). This could d do if assemblers were able to duplicate itself (forming duplicators). Once formed billions of assemblers, then we are ready to create an object.
Billions of assemblers and duplicators can only make the object less than 1 cm kubic, but with the increasing number assemplers and duplicators, we can form a larger object with a special ability.
In fact, we can duplicate diamonds, food and water.
In medical, cancer patients only drink liquids that contain nanorobot. Nanorobot will attack and alter the composition of the virus kanker.bahkan cells.
For women, nanorobots could be anti-aging (prevention of aging). And nanorobot also can assist in surgical operations, because it has a very small size and keen to do the surgery.
Even the scientists can make use of airborne nanorobots (nanorobot air) to strengthen the ozone layer.
Nanorobot also can purify water and reduce auto pollution. More extreme, we can create a nanoparticle such as petroleum, and we no longer need to mine oil.
Dangers of nanotechnology in the medical world:
because of the super small size, the nanoparticles are worried easily penetrate the layer between brain (the blood-brain barrier), the membrane that keeps the brain from harmful chemicals in stream darah.Jadi before we use nano technology with a very small particle, we must be sure that the particle will not poison us.
