Nanotechnology- the future is now We frequently hear in our daily life the term “Nanotechnology”. But, do we know what it is at first glance? Some of you may heard it for the first time in 90s, in the famous American science fiction drama television series: The X-files as the technology of the extraterrestrial intelligence. Nanotech is all around you, already: in clothing, electronics, manufacturing and increasingly in health and cosmetics. Actually, nanotechnology is nothing extraterrestrial and today, it’s used in many products, stain resistant fabrics, self- cleaning titles and paints. Then, what is Nanotechnology? To answer this question, first we need to answer what is technology? Technology is the application of science. We study the technology of the nature and then apply it to out contemporany world for our benefits. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. "Nano" means one-billionth. When materials are observed at the nanometer level (one-billionth of a meter), they often display unique properties. Today, researchers use advanced tools, such as the atomic force microscope, to measure matter at the nanoscale as well as to build entirely new materials, devices, and systems molecule-by-molecule. To understand better, here it’s a scale of objects with different sizes: at 10 -10 we find the Carbon atom, glucose molecule, at 10 -9 we find Buckyballs, carbon nanotubes (the strongest material yet discovered), at 10 -8 the we can see the DNA structure, at 10 -7 it can be found the virus structure, at 10 -6 some bacteries, at 10 -5 the red blood cells, 10 -4 is the measure of a human hair. Carbon can form the hardest material known on earth: diamond and it also can form one of the softest materials: graphite. Aside from the naturally occuring forms of carbon,graphite and diamond,
