What Is Nanotechnology?
“Nanotechnology will allow us to create new materials, devices, and systems with unprecedented properties and functions.”
– Ralph Merkle
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. This technology has the potential to revolutionize the way we live, from the way we manufacture products, to the way we treat diseases, to the way we deliver energy. Its potential applications are nearly limitless and range from the creation of tiny robots that can be used for drug delivery, to the production of ultra-strong materials, to the manipulation of light and energy. Nanotechnology is a rapidly developing field, with new breakthroughs and discoveries being made all the time.
How Nanotechnology Started
Nanotechnology first began in the early 20th century, with the development of the scanning tunneling microscope. This revolutionary device allowed scientists to view and manipulate atoms and molecules with unprecedented accuracy. With this newfound capability, scientists could begin to explore the tiny world of nanoscale particles and structures.
In the 1980s, the discovery of Fullerenes and Carbon Nanotubes opened up a new world of possibilities for nanotechnology. These carbon-based structures, which measure only one or two nanometers in size, have a wide range of novel properties and applications. Since then, nanotechnology research has expanded to encompass a variety of other materials, including metals, polymers, and quantum dots.
Today, nanotechnology is being used in many different fields, such as medicine, energy, electronics, and materials science. Scientists continue to investigate the potential of nanotechnology, and the possibilities for its future applications seem limitless. 
Who Coined the Term Nanotechnology?
The term nanotechnology was first coined in 1974 by Professor Norio Taniguchi of the Tokyo Science University. He defined nanotechnology as “the technology of manipulating and controlling matter on an atomic or molecular scale”. In 1986, Eric Drexler published his book Engines of Creation, which popularized the concept of nanotechnology and its potential applications. Since then, nanotechnology has grown exponentially in research and development, leading to the emergence of nanomaterials, nanodevices, nanosensors, nanobots, and other nanotechnology-related products and applications.
