NANO AND TECHNOLOGY
▪A Nanometre is a unit of length in the metric system, equal to one billionth of a metre (10-9).
▪Technology is the making, usage, and knowledge of tools, machines and techniques, in order to solve a problem or perform a specific function.

DEFINATION
•Nanotechnology is the study of manipulating matter on an atomic scale.
•Nanotechnology refers to the constructing and engineering of the functional systems at very micro level or we can say at atomic level.

HISTORY
▪The first ever concept was presented in 1959 by the famous professor of physics Dr. Richard P. Feynman.
▪He won a Noble Prize for ‘Fundamental Work in Quantum Electrode’.

HISTORY (contd..)
▪The term “Nano-technology" had been coined by “Norio Taniguchi ” in 1974
▪ Invention of the scanning tunneling microscope in 1981 and the discovery of fullerene(C60) in 1985 lead to the emergence of nanotechnology.

•The atomic force microscope (AFM).•The Scanning Tunneling Microscope (STM) are scanning probes that launched nano.•Various techniques of nanolithography such as:optical lithography,X-ray lithography,• Dip pen nanolithography, Electron beam lithography(inkjet printer) were also developed.•Lithography in MEMS is also an important aspect.

APPROACHES
• BOTTOM UP In the bottom up approach different materials and devices are constructed from molecular components of their own.They chemically assemble themselves by recognizing the molecules of their own breed.
• TOP DOWN In top down approach nano objects and materials are created by larger entities without bouncing its atomic reactions usually top down approach is practiced less as compared to the bottom up approach.
HOWEVER, Solid-state techniques can also be used to create devices known as nanoelectromechanical systems or NEMS, which are related to microelctromechanical systems or MEMS.

CARBON NANOTUBE
• Carbon nanotubes are allotropes of carbon with a cylindrical nanostructure.
• Highest strength to weight ratio, helps
in creating light weight spacecrafts.
• Easily penetrate membranes such as
cell walls. Helps in cancer treatment.

APPLICATIONS
• Enable drugs to be delivered to precisely the right location in the body and release drug doses on a predetermined schedule for optimal treatment.
• Nanobots can clear the blockage in arteries.
• In manufacturing bullet proof jackets.
• Making spill & dirt resistant, antimicrobial, antibacterial fabrics.
• The transistors are made of nanowires, that are assembled on glass or thin films of flexible plastic.

APPLICATIONS (CONTD…)
• E-paper, displays on sunglasses and map on car windshields.
• Size of the microprocessors are reduced to greater extend.
• This will also result in computers that consume less energy.
• Cutting tools made of nanocrystalline materials, such as tungsten carbide, tantalum carbide and titanium carbide, are more wear and erosion-resistant, and last longer than their conventional counterparts
• Aerogels lightest known solid due to good insulating properties is used in space suits and are proposed to use in space craft.

PITFALLS
• Nano-particles can get into the body through the skin, lungs and digestive
system, thus creating free radicals that can cause cell damage.
• The most dangerous Nano-application use for military purposes is the
Nano-bomb that contain engineered self multiplying deadly viruses that can continue to wipe out a community, country or even a civilization.
• Nanobots because of their replicating behavior can be big threat for
GRAY GOO.

NANOTECHNOLOGY IN INDIA
Starting in 2001 the Government of India launched the Nano Science and Technology Initiative (NSTI).
Then in 2007 the Nanoscience and Technology Mission 2007 was initiated with an allocation of Rupees 1000 crores for a period of five years. The main objectives of the Nano Mission are:- basic research promotion, - infrastructure development for carrying out front-ranking research, - development of nano technologies and their applications, - human resource development and international collaborations.

POSSIBILITES FOR THE FUTURE
•Nanotechnology may make it possible to manufacture lighter ,stronger and programmer materials that require less energy to operate and also be economical as well as eco-friendly
•The future of nanotechnology could very well include the use of nanorobotics.
•These nanorobots have the potential to take on human tasks as well as tasks that humans could never complete. The rebuilding of the depleted ozone layer could potentially be able to be performed.
