Sci-Fi Future - Nanotechnology
The Definition of Is Nanotechnology vague at best "the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes". "A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab]." It involves at or near Atom level of structures to build new materials and devices. One can consider the nanotechnology a continuation of the miniaturization cycle Example, the industrial and manufacturing process down to a billionth of a meter in size. How will it impact your life? Nanotechnology is rapidly becoming an interdisciplinary field. Biologists, chemists, physicists and engineers are all involved in the study of substances at the nanoscale.
Use Cases
Will it help ease the Pandemic? Nanomedicine is the application of Nanotechnology. https://en.wikipedia.org/wiki/Nanomedicine
How will it impact your next automobile purchase? https://www.researchgate.net/publication/283259275_Applications_of_Nanotechnology_in_Automobile_Industry
There is work being done in Nanotechnology for food safety. https://www.centerforfoodsafety.org/nanotechnology-in-food
A lot of the early offerings were built and based upon graphene, or carbon. Boron has been hot the last few years. The learning cycle for Nanotechnology is below.

Leaders
US Government has a Governing body known as The Nanotechnology Institute it can be found here - https://www.nano.gov/nanotech-101/what/definition
CDC Division known as NIOSH (AKA National Institute for Occupational Safety and Health) - https://www.cdc.gov/niosh/topics/nanotech/default.html
IBM & Samsung developed Nanosheets (AKA NS). A nanosheet is a two-dimensional nanostructure with thickness in a scale ranging from 1 to 100 nm. It can be prepared at room temperature
Above is just a short summary in this developing field.
Lots of new applications to this atomic scale technology.
Enjoy the Journey!
