In nanotechnology, structures of a size smaller than 100 nanometers (nM) are studied.

Nanocarn can hear faint sounds up to -60 dB. It can hear faint sounds up to one-millionth of the human hearing power.

The specific protein formed in cancer and Alzheimer's diseases through nanotechnology is the Signature Protein.

Nanotechnology is related to atomic engineering, where materials are manipulated at the atomic level.

Generations of nanotechnology:

1. First generation (2000 AD): Aerosols, Polymers
2. Second generation (2005 AD): Nanosensors, Nanocapsules, Nanochemicals, Nanodrugs, 3-D Transistors
3. Third generation (2010 AD): Nanorobots and 3-D Networks
4. Fourth generation (2015 AD): Molecular manufacturing

The term nanotechnology was first used in 1974 by scientist Norio Taniguchi of the Tokyo University.

Prof. C.N.R. Rao is known as the Father of Nano Technology in India.

One nanometer is equal to $10^{-9}$ meters.

Nanotechnology is based on the nanometer scale (1 to 100 nanometers). The structure and specificity of nanomaterials can be viewed and measured by electron microscopy.

The word 'Nano' is derived from the Greek word 'Nanos', which means dwarf. The credit for presenting the concept of nanotechnology to the world for the first time goes to physicist Richard Feynman, who was awarded the Nobel Prize in 1959.

In nanotechnology, materials of the nanometer scale ($10^{-9}$ meters) are studied and used.

In nanotechnology, the size of particles is between 1 and 100 nanometers. 1 nanometer is equal to $10^{-9}$ meters. Therefore, particles with a dimension less than $10^{-9}$ meters are called nanoparticles.

Nanotechnology is related to atomic physics because it works at the level of atoms and molecules.

The value of 1 nanometer is $10^{-9}$ meters.

Nanomaterial refers to a material whose structural components have dimensions of less than 100 nanometers. When one dimension of a material is reduced to the nano range, it is called a quantum well. If two dimensions are reduced, it forms a quantum wire, and if all three dimensions are reduced, it forms a quantum dot.

Quantum dots are semiconductor particles a few nanometers in size, possessing optical and electronic properties that differ from larger particles due to quantum mechanics. They are a central subject in nanotechnology.

Nanofiltration (nano filters) is a membrane filtration process often used to remove microorganisms or bacteria from liquids like water. In the nanofiltration technique developed in France for water purification, water is filtered through a special membrane, which has a pore size of 10 Angstroms.

India's first nano-cellulose plant developed by ICAR-CIRCOT (Central Institute for Research on Cotton Technology) Mumbai is related to cotton.

At the nano scale, the surface area to volume ratio increases, making friction and surface-related properties significant.
