Cancer, or any disease for that matter, begins and ends with the tiniest life force within the human body. These are the living cells that carry out the multiple complex functions necessary for life. Unfortunately, with today’s tools for diagnosis and surgical procedures, there is always the possibility that: damaged, infected and disease-carrying cells are overlooked (and thereby not eradicated by the treatment); and that the surgical procedure might actually do more damage as opposed to letting the disease run its course. It is not uncommon for cancer cells to metastasize to other organs in the body after removing the cancer afflicted part – even with aggressive chemotherapy. It is also not uncommon to hear patients dying from the surgical procedures or surgery patients suffering from the complications of the post operative treatments.
With nanotech, medicine has a fighting chance against cancer cells by producing diagnostic tools that can pinpoint the occurrence of cancerous growths as they happen; and by removing these in the cellular level that the afflicted body does not even have to be surgically opened. Nanotech has paved the way for various possibilities in diagnosis, cure and prevention of all possible diseases. Most of these are still a few technology tweaks along the way. However, the point is: the potential is now here and what may have been sheer impossibilities a good 50 years back are now becoming real by the minute. Right now, all eyes are focused on cancer research.
Cancer research with nanotech is particularly useful when it comes to the development and construction of smaller but more efficient cancer detection gadgets that can be easily replicated with the right technology. This means that formerly expensive diagnostic tools for cancer detection can now be made at more economical rates. Complex molecular machines can also be started on and developed further to help with correct and early disease diagnosis. One possibility that a lot of nanotech researchers are trying to develop are the molecular computers that not only works as a diagnostic tool but can be used as a search-and-destroy “operative” that can eradicate cancer cells on a cellular level. This is a proposed alternative to the various cocktails of medications and the series of medical procedures that one cancer patient has to endure just to slow down the process of cancer growth

NANOTECHNOLOGY AGAINST CANCER
PLEASE SEND ME YOUR IDEAS AND PROGRESS DONE BY SCIENTIST IN THE USE OF NANOTECHNOLOGY TO FIGHT AGAINST CANCER CELLS

NANOTECHNOLOGY
Nanotechnology is one of the emerging branches of Science and Technology which is based on the scale of nanometers. It can be defined as the application of science, engineering and technology to develop novel materials and devices in different fields in the nano-range i.e. in molecular size. One nanometer is equal to 10-9 of a metre i.e. 0.000000001 metre. One nano particle can be considered 5,000 to 50,000 times smaller than the diameter of a human hair.
.Namasthe and welcome to all those who are interested in pharmaceutical nanotechnology....This is my first step in the field of nanotechnology.....
ABC OF nanotechnology
Nanotechnology is classified under three main sub branches - Nanomaterials, Nanoelectronics and Nano-Biotechnology. Nanotechnology finds wide application in areas viz. environment, aerospace, telecommunications, solar energy and computing etc. This science is used to change the properties of materials, make advances in Biotechnology or to design other products. The study of nanotechnology needs the knowledge and application of other branches of Science viz. physics, chemistry, biology and engineering.
Application of Nanotechnology
Nanotechnology finds application in computers, Electronics/semiconductor industry, Materials science including textiles, polymers, packaging and medical-related devices. By the application of nanotechnology individual atoms or molecules can be controlled for manufacturing computer chips and other devices which are thousands times smaller than those created by the use of current technology. Nano particles are created by the
