Nanotechnology, often perceived as a modern phenomenon, has its roots shadowing centuries with hints of 'nano' appearing in traditional craftwork. But it wasn't until the 20th century that we laid the scientific foundation. The pivotal turn came with renowned physicist Richard Feynman's legendary lecture, "There's Plenty of Room at the Bottom," in 1959, where he envisioned control and manipulation of individual atoms and molecules. Although Feynman never used the term 'nanotechnology,' his idea is often credited for birthing nanotech's conceptual groundwork.
It wasn't until the 1980s that the term 'nanotechnology' was coined by K. Eric Drexler, in his book "Engines of Creation," laying out molecular nanotechnology's incredible potential. However, around the same time, technologist Norio Taniguchi had used 'nanotechnology' to describe semiconductor processes that operated at the nanometer level.
The booming '80s also saw the development of the scanning tunnelling microscope by IBM Zurich's Gerd Binnig and Heinrich Rohrer, offering the means to 'see' atoms for the first time. This brought about an era of exploration and manipulation at the atomic level, a feat that earned them the 1986 Nobel Prize in Physics.
Further fuelling the growth of nanotechnology was the discovery of fullerenes or Buckyballs in 1985. Named after Buckminster Fuller, renowned for his geodesic domes, these hollow, soccer ball-shaped molecules marked the first in a class of entirely new carbon molecules - the third form of carbon after diamond and graphite. The three scientists behind the discovery - Robert Curl, Harold Kroto, and Richard Smalley - were awarded the Nobel Prize in Chemistry in 1996.
Developments continued into the 21st century with the design and synthesis of new nanoscale materials, like carbon nanotubes and quantum dots. From Feynman's vision, through Nobel-recognized innovations, to the present, nanotechnology has profoundly influenced fields from electronics, medicine, and energy, revamping products with nanocoatings to nano-circuitry. This encapsulates a tiny slice of the vast history of nanotechnology, a field propagating huge impacts from the very minuscule.
Nanotechnology's stride into the 21st century brought forth a transformative application: nanocoatings. The technology was spurred by developments in the late 20th century, specifically the advent of tools like the Scanning Tunnelling Microscope, enabling atom-scale manipulation. The discovery of natural nanoscale materials, like fullerenes, gradually led to engineered materials for specific applications, marking an initial step in advanced nanocoatings. The turn of the millennium saw nanocoatings evolve into offering multi-functional properties such as anti-corrosion, self-healing, and thermal resistance. Whilst tightly interwoven with the broader canvas of nanotechnology, the journey of nanocoatings is a testament to the nuanced and diverse applications of this disruptive technology.
In 2023, the Nobel Prize in Physics was awarded to Pierre Agostini, Ferenc Krausz, and Anne L'Huillier. The researchers' breakthroughs in ultrafast and nanoscale physics underscored the continuing impact of nanotechnology in the scientific world, affirming its relevance and importance in uncovering new aspects of the physical world captured in the minuscule, yet powerful, nano-scale.
