What is nanotechnology?• Nanotechnology is the manipulation of matter to make it do what we want it to do at the molecular or Nano scale.
How Small Is Nanotechnology?• Ant 5 million nanometers long• A red blood cell 7500 nanometers long• A dna 2nm long
The three main points• 1/ The use of nanotechnology to manipulate molecules in order to form better products.• 2/ The use of nanotechnology in medicine• 3/ The use of nanotechnology in energy
I/The use of nanotechnology in order to formbetter products.• “Nanotechnology will let us build computers that are incredibly powerful. Well have more power in the volume of a sugar cube than exists in the entire world today”. Ralph Merkle• A-Nanotechnology is an enabling technology. Ralph Merkle is a researcher on the molecular nanotechnology
• B- Nanotechnology will change everything that man made during this century.But what does nanotech offers us today? • 1/Nanotech can make materials germ free. 2/It can eliminate bad odors. 3/It can be used to strengthen materials
II/The nanomedicine• “If we can reduce the cost and improve the quality of medical technology through advances in nanotechnology, we can more widely address the medical conditions that are prevalent and reduce the level of human suffering”. Ralph MerkleRalph Merkle is a researcher on the molecular nanotechnology
How Nanomedicine can cure cancer?• Nanotechnology has been used for the first time to destroy cancer cells with a highly targeted package of "tumor busting" genes.• Its benefits:• Deliver nanoparticles directly to the cancer tissues• Minimize undesirable toxicity to the rest of the body• This nanoparticle therapy leads to the extermination of the tumor from the body.• It does not leave Secondary Effects on the body.
Other uses of Nanomedicine• Nanomedicine can be used to:• Clean arteries• Attack viruses• And even to reverse the aging process.• All of those uses can be done by a revolutionary object named the “nanorobot”. How is that?
Nanorobots• The entry of nanorobots will literally revolutionize the world of medicine. These miniature devices would not only be able of entering into the body and detecting the diseases and infection, but they will also be able of repairing internal injuries. N
III/ Nanotechnology & Energy:• Nanotechnology is being used in several applications to improve the efficiency of energy generating.
What Are Its Benefits?A-Increase the electricity generated by windmills.B-Generating electricity from waste heat.C-Clothing that generates electricity.
