Nanotechnology and medicine
Nanotechnology will provide new tools for madicine. It could radically change the way surgery is done. It will make it possible to do molecular scale surgery to replace defective cells, repair and rearrange cells. Since disease is the result of physical disorder, misarranged molecules and cells, medicine at this level should be able to cure most diseases. Mutations in DNA could be repaired and cancer cells, toxic chemicals and viruses could be destroyed through the use of medical Nanodevices.
Nanotechnology has found innumerable applicationsin the field of medicine, particularly in treatment of cancer. It has the Power to radically change the way cancer is diagnosed, imaged and treated. Currently, there is a lot of research going on to design novel nanodevices capable of detecting cancer at its earliest stages, pinpointing its location within the body and delivering anticancer drugs specifically to malignant cells.

Nanotechnology Used to Measure Low Concentrations of Cyanide Ion in Water
Iranian researchers successfully measured low concentrations of the toxic and harmful cyanide ion in aqueous environments by using nanotechnology. "Synthetic Silver nanoparticles were used in the research as the colorimetric sensor in order to measure low concentrations of cyanide ion in aqueous environments," Salahoddin Hajizadeh, MSc in analytical chemistry from Urmia University, told the INIC. ...Full article
Creating a transistor with a single atom
In Technology there is a strong desire to shrink things. Consider the sheer amount of news these days surrounding nanotechnology: it is arguably one of the fastest growing sectors in technology. Recent news out of two universities on potentially groundbreaking work on single-atom transistors should not be that surprising, then. Scientists have created a transistor the size of a single atom, opening the way for the next generation of nanotechnology: a quantum computer that might one day function in a nanoscale world and would be significantly smaller and quicker than today's silicon-based machines. Until now, single-atom transistors were created on a hit-or-miss basis....Full article
Entire Medical Lab in a high powered chip
Recent developments in Nanotechnology and medicine makes it possible to put an entire medical lab into one high-powered chip, which not only fits in the palm of your hand, but also performs diagnostic tests in a matter of minutes. Researchers are gradually finding ways to create reliable, nano-sized labs that are able to perform a variety of diagnostic tests, which used to require teams of people and weeks of waiting. The tiny wafers of glass or plastic work by compressing a series of tests. For example, the Guardian reports Professor Tom Duke at the London Center for Nanotechnology is working on a "lab-on-a-chip" to test for HIV.

Carbon nanotube 'muscles' could aid drug delivery
Artificial muscles strong enough to rotate objects 1,000 times their own
weight have been invented by an international team of researchers.
The development could lead to the realisation of a propulsion system for nanorobots that can deliver drugs or remove parasites. Using yarns of carbon nanotubes, the researchers developed artificial muscles that can rotate 250° per millimetre of muscle length. ...Full article
