FAQ
What Is Nanotechnology?
Nanotechnology is science, technology, and engineering conducted at a scale of about 1 to 100 nanometers. Nanotechnology and nanoscience are the application and study of exceptionally small things and can be applied across all other science fields, including biology, chemistry, physics, and materials science.
When Did the Concept of Nanotechnology First Emerge?
The concepts that resulted in the development of nanotechnology were discussed for the first time in 1959 by Richard Feynman, the renowned physicist, in his talk, There’s Plenty of Room at the Bottom. However, the term ‘nanotechnology’ wasn’t used until 1974 when it was coined by Norio Taniguchi.
What Is the National Nanotechnology Initiative?
The National Nanotechnology Initiative was a move by the US Government to fund and promote research into nanotechnology. It formalized the size-based definition of nanotechnology and also established funding for research regarding the nanoscale. In Europe, the Framework Programmes for Research and Technological Development initiative fulfilled a similar function.
What Are the Two Main Approaches in Nanotechnology?
In nanotechnology, there are two main approaches: ‘bottom up’ and ‘top down.’ In the former, devices and materials are constructed from molecular components that chemically assemble themselves via the principle of molecular recognition. In the latter approach, nano-objects are built without atomic-level control from larger entities.
What Is the Nature of Nanomaterials’ Dimensions?
In terms of dimensionality, nanomaterials can be 0D, 1D, 2D, and 3D. Dimensionality plays a key role in identifying the characteristics of nanomaterials, including chemical, physical, and biological traits. Nanomaterials with smaller dimensions have a higher surface area compared to 3D nanomaterials.
How Is Nanotech Being Used in Everyday Products?
Silver nanoparticles are now being infused in bandages to promote faster healing, while ‘passive’ nanomaterials are regularly used in items including sunscreen, cosmetics, surface coatings, paint, cleaning products, and more.
What Are the Potential Applications of Nanotechnology?
It is possible that nanotechnology can be used to create a wide range of new devices and materials that have a large number of applications. These include nanomedicine, biomaterials energy production, nanoelectronics, and consumer products.
What Are the Advantages of Making Materials at the Nanoscale?
Materials made at the nanoscale have enhanced properties such as being more lightweight, stronger, having increased control of the light spectrum, and greater chemical reactivity.
How Small is One Nanometer?
One nanometer is equal to a billionth of a meter. Comparatively, if a marble was the same size as a nanometer, the size of the Earth would be one meter.
