"the next big thing is really small"

Future of Nanotechnology

"Whether you are the CEO of a multi-billion dollar corporation, a heart surgeon, an automobile shop manager, a drug company representative, a psychiatrist, or even a house painter, Nanotechnology is going to impact you."

The future of Nanotechnology.  Nanotechnology is improving everyday.  Things are being made and discovered everyday.  But lots of things are being predicted.  Within a decade, Nanotechnology is expected to be the mainframe of 41 trillion worth of products in the United States alone.  And also will get people from 2 to 8 milion new jobs.

For example, in the future there will be different type of packaging that will be in use widely. It will be called " smart" and it will indicate for example, the freshness of the food wrapped inside.  Also the next wave could be in Bio-medicine, which includes dramatic new ways of delivering drugs, and new medical implants.  If we continue research in Nanotechnology we also will be able to create machines that will be able to fabricate an entire new generation products which are cleaner,stronger, lighter, and more precise.

If we continue these trends we will develop a new manufacturing tehnology that will let us inexpensively build complex systems such as computers with far superior quality than the current manufacturing systems.

Products also will be designed in days and can be distributed in a matter of days as compared to months it takes now.  Products can also be pre-designed.  There are lots of things that will be reveled in Nanotechnology as we go along, and this technology is going to change our lives in a far more significant way than any other breakthrough technology that we have experienced sofar.

Nanotechnology to help solve world's water shortage 

<>NanoWater congress met in Amsterdam in October 2004 to discuss how nanotechnology applications can help solve the world's water shortage. The NanoWater congress, which kicked off the 2004 water-technology trade show, outlined how nanotechnology can create drinking water from contaminated water, salt water and all forms of waste water. 

The promise of nanofiltration devices that "clean" polluted water, sifting out bacteria, viruses, heavy metals and organic material, is driving companies which developed technology used in Brita filters, to make nanotechnology-based filters for consumers. Two products incorporating nanotechnology are going to hit the market within the next year and are already being tested in certain countries.

Internet heading to Light speed with Nanotechnology

A new nanotechnology that eliminates network bottlenecks could help create a web surfers' paradise that is 100 times faster than today's internet.

Fiber-optic networks capable of sending information at 10 Gbps or 40 Gbps are being rolled out around the world and under the oceans to connect everyone to everything. But getting information to pass from one high-speed network to another can be slowed by electronic switching technology.

The new technology, described in a paper published Aug. 11,2004 in the scientific journal Nano Letters, uses buckyballs glued together by a custom polymer, providing a way to create an optical switch.

Darker side of Nanotechnology

The nanotechnology researchers and industry collectively cringed in April, 2004 after a study showed that fish exposed to nanoparticles suffered brain damage.  There are several scientists and critics who say the much-hyped nanotechnology also has several dark sides which could cause harm to human beings and environment in future.

To see what might happen if nano-sized particles called fullerenes (known popularly as buckyballs -- which are extremely stable arrangements of carbon atoms that look like soccer balls) got into the environment, Eva Oberdörster, an aquatic scientist at Southern Methodist University, Texas, put some buckyballs into a fish tank at a concentration of 0.5 parts per million, along with nine largemouth bass fish. The buckyball-breathing fish experienced significant brain damage after 48 hours. Brain-cell membranes were disrupted, much similar to illnesses such as Alzheimer's disease in humans.

Sorting out the impacts of nanotech won't be easy, since the properties of nanomaterials are not well-defined yet. Something such as gold -- which is normally harmless, -- is highly reactive and likely to disrupt biological processes when it's nanosized.  And then there's the problem of trying to detect particles of such a tiny size. Microscopes powerful enough to identify nanoparticles are just being developed.
