NANO WORLD
This paper presentation is to create awareness among the people of our country about the importance of nanotechnology.
Over the past decade a new term has entered our vocabulary and the word is NANO. We hear the word in movies. Its mentioned on television and in newspaper and magazines. Future says “IT WILL PAVE THE WAY FOR UNIMAGINABLE POSSIBILITIES”. Nothing in the world is free from nano. Nanotechnology is preferred because of its special properties. The usage of this technology provides a pollution free environment.
WHAT IS NANO?
NANO is actually a prefix that comes from the greek word for dwarf (small) means one billion. So one nanometer is one billionth of a meter. Nano is something 80,000 times smaller than the line of our fingerprint. Nano can also be termed as a tiny molecule.
WHAT IS NANOTECHNOLOGY?
Nano technology is an idea that most people simply did’nt believe. Just as silicon transistor replaced old vaccum tube technology and enabled the electronic age, carbon nano devices could open a new era of electronics. Nano technology is the base technology of an industrial revolution in the 21 st century. Those who control nano technology will lead the industry. Technically, It is “STUDY OF NANO “ (ie) study of controlling of matter on an atomic and molecular scale. Generally, nano technology deals with the structure size between 1 to 100 nanometer in atleast one dimension and involves developing materials or devices within that size .In other words NANO TECHNOLOGY refers to the projected ability to construct items from the bottom up using techniques and tools being developed today to make complete , high performance products .
IMPACT OF NANOTECHNOLOGY:
The impact of nano technology extends from its medical , ethical , mental , legal and environmental applications , to fields such as engineering , biology, chemistry , computing , material science , military applications and communication.
NANO IN TREATMENT FOR CANCER:
Nanotechnology offers the opportunity to study and interact with normal and cancer cells in real time, at the molecular and cellular scales, and during the earliest stages of the cancer process.
There are various methods in which cancer can be detected and cured. But in most of the methods, after the treatment of cancer, produces a lot of side effects that are very difficult to manage. But one of the efficient way to cure cancer is by using NANO X-RAYS.
This NANO X-RAY treatment is very useful to cure all types of cancer with non-toxicity.
Generally, Cancer is a harmful disease which inhales an abnormal growth of malignant cells that leads to destroying of organs, tissues, etc, . Cancer become tedious when the malignant cells under go mutation and spreads through the blood cells in our body and affects other organs of human body. The commonly used treatment is the STANDARD RADIOTHERAPY TREATMENT. This treatment makes the x-rays to radiate on cancer affected human body. These rays reacts with water( H-O-H) to produce free radicals(Rn). These free radicals produces bond with cancer cells and dna, so that it not only destroys the tumored cells but also produces healthy tissue damage. So this treatment produces toxicity to human body.
NANOTECHNOLOGY IN MOBILES AND COMPUTERS:
Today’s world cannot move without mobiles. Mobiles had become one of the essential resource to sustain in this world. But day by day the features and technologies are implemented in mobiles to improve its flexibility with we users. And for every newly implemented techniques the base technology is NANO TECHNOLOGY.
At 20th century there came the evolution of computers. But at 21th century the world is drowned by the intelligence of mobile technologies.
Touch mobiles are liquid electronics were the liquids consists of nano particles. Nano has a feature of transferring information more than a micro chip can. Nano chips has a larger capacity than silicon chips/micro chips. MIKRON is the only factory that produces nano chips. The flexibility in mobiles are also due to nano molecules. The nano cutter can be used to convert micro sim to nano sim for iphone 5.
CONCLUSION:
The drawback of this technologies are
Global monetary crisis,
loss of jobs because of more dependency on machines,
oil becomes worthless because ,
atomic weapons more destructive and accessible.
In relation to health problems, it is so minute that its existence in the hand is much unnoticed.
The risk of inhaling this could be very dangerous, due to which it can be a cause of death.
