- Nano means small (10^-9 m) but of high potency, and emerging with large applications piercing through all the discipline of knowledge, leading to industrial and technological growth.
- Nano-sized structure needs to be magnified over 10 million times before we can easily appreciate its fine detail with the naked eye.
- Nanotechnology is already having its impact on products as diverse as novel foods, medical devices, chemical coatings, personal health testing kits, sensors for security systems, water purification units for manned space craft, displays for hand-held computer games, and high-resolution cinema screens. Nanotechnology is expected to have an impact on nearly every industry.
- The U.S. National Science Foundation has predicted that the global market for nanotechnologies will reach $1 trillion or more within 20 years.
WHAT IS NANO TECHNOLOGY?
Nanotechnology is a catch-all phrase for materials and devices that operate at the nanoscale. In the metric system of measurement, "Nano" equals a billionth and therefore a nanometer is one-billionth of a meter.
Nanotechnology is a multidisciplinary science that has its roots in fields such as colloidal science,device physics and supramolecular chemistry.
NANOTECHNOLOGY is a fundamental, enabling technology, allowing us to do new things in almost every conceivable technological discipline. Nano means small (10^-9 m) but of high potency, and emerging with large applications piercing through all the discipline of knowledge, leading to industrial and technological growth.
As the prefix nano indicates extreme smallness. So small, in fact, that a nano-sized structure needs to be magnified over 10 million times before we can easily appreciate its fine detail with the naked eye.
Nanotechnology refers to technologies in which matter is manipulated on the atomic and molecular scale to create novel materials and processes. It is not just the study of the very small; it is the practical application of that knowledge. There are two main routes of entry to the nano-world:
Nanotechnology and its development is defined by key policy makers, as the development of nanotechnology as the latest mega trend in science and engineering which will bring a wave of radical innovation and perhaps, because of its potentially broad impact, spark new industrial revolution in various application areas1.Areas of applications include immediate impact - drug delivery to treat tumor, cancer (without using radiotherapy & chemotherapy), solar energy, batteries, display technologies, opto-electronic devices, semiconductor devices in nanoelectronics, biosensors, CNT's etc., nanocomposites such as Al2O3 oxides, catalysis, and luminous paints.
