Shaping memory materials
Nanotechnology introduced the techniques to distort the plastic and silicon structures, which allowed the recovering of original shape of the material. This technology is named as SMM shaping memory materials. Metals and aluminum are reshaped and processed at nano scale to produce a chip, which can store bulk of information on it. Aluminum and silicon distortion was impossible before the arrival of nanotechnology
Assemblies and Chemical sensitivity of porphyrin
Porphyrins is the element with the unique binding properties that are widely exploited in natural world to attain beneficial and essential functions for life, nanotechnology has provided the most accurate and real some the mimic of these functions with synthetic counterparts which provides the basis of chemical bonding and sensitizing
Metal oxide nanowires as chemical sensors
Another impressive feature of nanotechnology is that it made possible for the scientists to use metal oxides as the sensors. When metal are treated at nano scale they can carry huge amount of electrons and can be used as chemical sensors. , this was discovered in early nineties and nanowires were introduced.
Use of nanomaterials for water purification
Nanotechnology allowed the researchers to process the materials to be used in purification of drinking water such as sand, soil and even glass. Nano filtration plants are present in the developed countries of the world. Nanomaterials can purify water up to 99.9 percent without affecting the original flavor the water. it was seen for the first time that nanotechnology can extract the safest drinking water.
Self-assembling the key feature of nanotechnology .there is no other technology in which molecules under processing can rearrange themselves easily. Molecular nanotechnology can produce many new components from the existing ones by simply rearranging themselves.
Miniaturizing mechanical surgery
Recent advances in sub-millimeter scale engineering showed the excellent work of nanotechnology in the field of medical sciences .nanotechnology introduced such devices, which do not even leave a scar after major surgeries. it has also miniaturized the surgical instruments which are used in the diagnostics and therapeutics applications.
Fabrication of electronic biosensors
Nanotechnology introduced the nano fabrications, which has reduced the cost of some of the major health equipment that includes electronic biosensors. Detection biosensors, which are nanoly, structured detect and displays highly revolutionized images.
New carbon nanotubes AFM technology
Nanotechnology also ha great value in the field of nuclear sciences because of its extra ordinary features to increase the atomic force. it was discovered in mid nineties that uranium if processed at nano level can empower the five times more powerful nuclear bomb. Nanotechnology enlighten the nano particle of carbon, .nanotubes of carbon are used to build ultra sharp tips for cutting the rigid surfaces. The technology of the new carbon tubes is named as AFM (Atomic Force Microscopy). The technology is used for the fabrication of probe tips with ultra sharp points .AFM is also used for synthesizing and for developing new components.
General Purpose technology
Nanotechnology can create machines, peripheral home appliances with best functioning until now. It is the only technology, which is general purpose. From Light Emitting Diodes (LEDs) to socks, all are processed at atomic scale for increasing and improving the quality of the product.
