NANOTECHNOLOGY:
Nanotechnology refers to the branch of science and engineering devoted to designing, producing, and using structures, devices, and systems by manipulating atoms and molecules at nanoscale, i.e. having one or more dimensions of the order of 100 nanometres (100 millionth of a millimetre) or less.
KEY TECNOLOGY:
Nanotechnology has revolutionized the electronics industry by enabling the manufacture of nano-scale components, such as field-effect transistors (FET), flash memories, and integrated circuits. These smaller, more efficient components enable more powerful, faster, and energy-efficient electronic devices.
ADVANTAGES:
Nanotechnology also lowers costs, produces stronger and lighter wind turbines, improves fuel efficiency and, thanks to the thermal insulation of some nanocomponents, can save energy. The properties of some nanomaterials make them ideal for improving early diagnosis and treatment of neurodegenerative diseases or cancer.
DISADVANTAGES:
Nanotechnology can even be used in the future to treat lifethreatening diseases like cancer. However, it does have some drawbacks, for example, toxicity, environmental harm and organ damage caused by nanoparticles. There are some ethical issues concerned with the use of nanotechnology too.
USES OF NANOTECNOLOGY:
EXAMPLES AND APPLICATIONS OF NANOTECHNOLGY

HOW IT WORKS?
Nanotechnology provides a link between classical and quantum mechanics in a gray area called a mesoscopic system. This mesoscopic system is being used to manufacture nano assemblies of nature such as agricultural products, nanomedicine, and nanotools for treatment and diagnostic purposes in the medical industry .
