I often think that how rapidly the digital world changed our way of living. Today all that technologies have become part of our lives, and how Science plays an important role in our lives same way the technology also plays major role in our day today lives.
Today Science has attained more importance along with technology because the technology has helped Scientists in their important researches. The development of technology in Science has helped to find solutions to many problems. There is one technology which is playing an important role in the development of Science is the ‘Nanotechnology’.
Nanotechnology is Science, engineering, and technology conducted at the nanoscale. Nanotechnology is the study and application of extremely small things and can be used across all the other Science fields, such as Chemistry, Biology, Physics, Material Science, and Engineering.
The ideas and concepts behind Nanoscience and Nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by Physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term Nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term Nanotechnology. It wasn’t until 1981, with the development of the scanning tunneling microscope that could “see” individual atoms, that modern Nanotechnology start.
Nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, Nanotechnology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high-performance products.
Two main approaches are used in Nanotechnology, bottom-up and top-down. In the “bottom-up” approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the “top-down” approach, nano-objects are constructed from larger entities without atomic-level control.
Nanotechnology involves the understanding and control of matter at the Nanometer-scale. The so-called Nanoscale deals with dimensions between approximately 1 and 100 nanometers.
Nanotechnology can increase the surface area of a material. This allows more atoms to interact with other materials. An increased surface area is one of the chief reasons nanometer-scale materials can be stronger, more durable, and more conductive than their larger-scale.
Nanotechnology can help medical tools and procedures be more personalised, portable, cheaper, safer, and easier to administer. Silver nanoparticles incorporated into bandages, for example, smother and kill harmful microbes. This can be especially useful in healing burns.
Nanotech is also furthering advances in disease treatments. Apart from medical Nanotech also be used in food, electronic industries. Nanotech has improved display screens on electronic devices. This involves reducing power consumption while decreasing the weight and thickness of the screens.
The food industry is using nanomaterials in both the packaging and agricultural sectors. Clay nanocomposites provide an impenetrable barrier to gases such as oxygen or carbon dioxide in lightweight bottles, cartons, and packaging films.
