What Is Nanotechnology?

Introduction: The Nano Revolution Begins

The world is entering the brand new era – Nano Revolution, a time when science hereto is at the scale of a millionths less than the diameter of a human hair. What Is Nanotechnology is about the materials and devices that are made at the atomic and molecular scale which result in innovations that were never considered before.

Nanoscience has revolutionized all facets of human life due to more robust machinery and improved electronics, precise drug delivery, and renewal energy. Well, guess what, clothes that never are washed, medicines that locate and kill cancer cells, and solar panels that nearly collect and use all of the sunlight — all of this happened through What Is Nanotechnology.

It is not only a revolution on small matters but on smart, efficient, smart and sustainable matters. With scientists trying to unravel this world of invisibility, What Is Nanotechnology promises to define the future of health care and the work environment, and communication and daily living. The nano revolution really is the giant leap in human development and it is the way of defining anew how we perceive the matter itself and how we use it.

Historical Evolution of Nanoscience

Development of Nanoscience: From Concept to Fabrication

Nanotechnology has a span of decades, starting with conceptual prediction and growing into practical tools and applications. While many link this new area of science to a famous lecture, the full historical context includes the works of two more influential figures, Norio Taniguchi and Eric Drexler.

The Conceptual Seed (1959): Richard Feynman

The conceptual basis of what is nanotechnology is commonly considered to be physicist Richard Feynman. In his famous 1959 talk, entitled “There’s Plenty of Room at the Bottom”, Feynman presented the notion of controlling matter on scales that enable the control of individual atoms and molecules. It was a theoretical provocation to present the possibilities of ultra-miniaturization long before the tools to implement it had been invented.

The Termite (1974): Norio Taniguchi

The notion of what is nanotechnology as a defined term further evolved with its introduction, much later, in 1974 by Japanese scientist Norio Taniguchi of the Tokyo University of Science.

Taniguchi used this terminology to refer to a paper focused on the order of required precision to machine materials with tolerances finer than a micrometer, and in fact specified a range of dimensions in the nanometer range (one billionth of a meter).

Molecular Assemblers Vision (1980s): Eric Drexler.

The contemporary, futuristic idea of what is nanotechnology is called Molecular Nanotechnology (MNT) brought into most modern popularity by American engineer Eric Drexler.
In the late 1980s, Drexler published the book Engines of Creation: The Coming Era of Nanotechnology. In that book Drexler proposed the idea of molecular assemblers and nanobots: tiny machines (and replicators) that are able to position management of individual atoms and molecules, and build complex structures.
Drexler was able to shift the focus from precision engineering to bottom-up construction. He envisioned a world in the future where everything could be built up from the bottom small things to the larger: all things could be made from the bottom up atom by atom. Drexler’s theoretical schema has provided inspiration for the following generations of nanoscientists and researchers.
This arc of progression—from Feynman’s theoretical idea, to Taniguchi’s technical term, to Drexler’s radical molecular vision—gives us a complete historical context of what is nanotechnology and the progress of nanoscience into the idea of what nanoscience means today.

Understanding the Nanoscale: Principles and Dimensions

 

Nanoscale: principles and dimensions biology of the nanoscale Systems at the nanoscale Interfaces at the nanoscale 

Definition Nanoscale means 1-100nm; 1nm=1 billionth meter.

• Quantum Effects : Because of their interactions, What Is Nanotechnology explains that the behaviour of electrons and photons is not the same but shows discrete values of electric charge and unique optical/electrical properties.
• Modification of Properties : Not only are What Is Nanotechnology materials different in color, strength, conductivity, and even melting point than the bulk materials (e.g., gold nanoparticles are red/purple). 
• Carbon Nanostructures : Carbon constitutes nanotubes or graphene that are highly strong, light in weight and conductive. 

Significance The behavior at nanoscale is imperative to the design of materials of improved mechanical, electrical or chemical characteristics.

Nanotechnology works on very tiny particles which are smaller than a cell into structure . It only focuses on working at atomic and molecular level. 

There are mainly Four important mechanisms that help it work: 

1. Self-Assembly : In this process, atoms or molecules are arranged automatically into an organized structure. It is like how puzzle pieces fit together on their own. What Is Nanotechnology uses self-assembly to build nanostructures, coatings.
2. Molecular Manipulation : In this atoms or molecules are rearranged by using special tools such as the Scanning Tunneling Microscope (STM) or Atomic Force Microscope (AFM), scientists move or control single molecules to build new materials. It is like shaping things molecule by molecule. 
3. Bottom-Up Engineering : What Is Nanotechnology builds big structures from small particles, starting from the bottom level (atoms) and going up, instead of cutting large parts into smaller pieces of material.

Self-Assembly	Molecules spontaneously organize into structures using forces like hydrogen bonds.	Creating DNA origami or lipid bilayers.
Molecular Manipulation	Using tools (like AFM/STM tips) to directly move individual atoms into specific positions.	‘Writing’ patterns on a surface atom-by-atom.
