Nanotechnology is the use of science, engineering, and technology at the nanoscale, or between 1 and 100 nanometers.
Nanoscience and nanotechnology, which study and use very small objects, are applicable to all other scientific disciplines, including chemistry, biology, physics, materials science, and engineering.
It’s difficult to grasp how tiny nanotechnology is. One nanometer, or 10-9 of a metre, is one billionth of a metre. Here are some concrete examples:
25,400,000 nanometers make up one inch.
An average newspaper sheet has a thickness of 100,000 nanometers.
Comparatively, if a marble were a nanometer, the size of the Earth would be one metre.
The visibility and manipulation of specific atoms and molecules are key components of nanoscience and nanotechnology. Atoms make up every single item on Earth, including the food we consume, the clothing we wear, the homes and structures we live in, and our own bodies. However, an atom is too small to be seen with the human eye. With the standard high school science microscopes, it is actually difficult to see. The early 1980s saw the development of the microscopes required to view objects at the nanoscale.
The era of nanotechnology began when researchers got the appropriate equipment, such as the scanning tunnelling microscope (STM) and the atomic force microscope (AFM).
Nanoscale materials have been utilised for centuries, despite the fact that current nanoscience and nanotechnology are relatively new. The hues in the mediaeval cathedrals’ stained glass windows were produced by different-sized gold and silver particles hundreds of years ago. Simply put, the artists of that time were unaware that the techniques they employed to produce these exquisite works of art actually caused modifications to the chemical makeup of the materials they were using.
