The age of development in the nanotechnology
came up to the drastic changes. Interface and colloid science had existed for
nearly a century before they became associated with nanotechnology. In the
language of chemistry, a colloid is a mixture in which one constituent of
microscopically dispersed insoluble particles is suspended throughout another
substance. Such as milk which a natural example of colloid. Earlier interpretations
and size measurements of nanoparticles had been made during the first decade of
the 20th century by Richard Adolf Zsigmondy (Winner of the 1925 Nobel Prize in
Chemistry) he investigated detailed of gold solutions and other nanomaterials
measuring sizes down to 10 nm using an Ultra-microscope which was capable of
visualizing particles as smaller as light wavelength. Notably, Zsigmondy was
the first who used the term "nanometer" explicitly for characterizing
particle size. Early in the 1920s, Irving Langmuir (Winner of the 1932 Nobel
Prize in Chemistry) with Katharine B. Blodgett introduced the concept of a
monolayer. Monolayer means a layer of
material which is one molecule thick. Now we can imagine how many thin it was?
In the early 1950s, Derjaguin and Abrikosova conducted the first measurement of
surface forces. They were don’t know, they started their journey to the
advanced theory to colloids and going to grab a Noble prize in physics.
There is close relation between reality and fiction …@Rst
Majority of the science fiction writers
illustrated the technology and its risk factors in sweet but short manner even
we read them with very enthusiasm. Kim Eric Drexler, In his 1986 book “Engines
of Creation: The Coming Era of Nanotechnology”, used to elaborate the
details of the use of nano-scale assemblers that have the capability to build
copy itself. Further, these tiny machines can build objects atom by atom. He
also coined the “grey goo” term which he used to describe what happens if
molecular nanotechnology was to go amiss. In this manner he also forespeaks the
concerns related nanotechnology. He published his doctoral thesis at Massachusetts
Institute of Technology (MIT) and the after some years it was turned into a
book “Nanosystems: Molecular Machinery Manufacturing and Computation”. The
book consisted broad overview of how molecular manufacturing will make products
by using nanoscale mechanical and robotic technologies to guide the placement
of molecules and atoms. The book was recognized as the Best Computer Science
Book award for 1992 from the Association of American Publishers. In
1986, Drexler with his wife co-founded the Foresight Institute, in
California. It is a non- profit organization which sought to edify society
about both the potential benefits and perils of nanotechnology.
