2. A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' 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.

3. When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a fewnanometers wide—motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties.K.

4.  Much of the work being done today that carries the name 'nanotechnology' is not nanotechnology in the original meaning of the word. Nanotechnology, in its traditional sense, means building things from the bottom up, with atomic precision. This theoretical capability was envisioned as early as 1959 by the renowned physicist Richard Feynman.Richard Feynman

5.  Mihail (Mike) Roco of the U.S. National Nanotechnology Initiative has described four generations of nanotechnology development (see chart below). The current era, as Roco depicts it, is that of passive nanostructures, materials designed to perform one task. The second phase, which we are just entering, introduces active nanostructures for multitasking; for example, actuators, drug delivery devices, and sensors. The third generation is expected to begin emerging around 2010 and will feature nanosystems with thousands of interacting components. A few years after that, the first integrated nanosystems, functioning (according to Roco) much like a mammalian cell with hierarchical systems within systems, are expected to be developed.four generations

6.  Nanotechnology is being used to make surfaces self-cleaning and stay clean for a long time. Nanotech can be found in cosmetics, sunscreens, clothing and many other consumer products today.

7.  The burgeoning interest in micro technologies, partly triggered by the rapid growth of nanotechnology, is opening up a floodgate of opportunities for developing new, micro-electromechanical systems (MEMS) based applications and products.  "The hunt for the `next big thing' is on," says Technical Insights analyst Jagan Ramaswami. "MEMS -- particularly bio MEMS, RF MEMS and optical MEMS -- are potential candidates in the search for a `killer application' by the research community."

8. The use of nanotechnology in cancer treatment offers some exciting possibilities, including the possibility of destroying cancer tumors with minimal damage to healthy tissue and organs, as well as the detection and elimination of cancer cells before they form tumors.

9.  Most efforts to improve cancer treatment through nanotechnology are at the research or development stage. However the effort to make these treatments a reality is highly focused. For example, The Alliance for Nanotechnology in Cancer, established by the U.S. National Cancer Institute, is fostering innovation and collaboration among researchers to resolve some of the major challenges in the application of nanotechnology to cancer. In addition, there are many universities and companies worldwide working in this area. It is possible that these efforts will result in cancer becoming being nearly eliminated in a decade or so, in the same way that vaccines nearly eliminated smallpox in the last century.

10. Today nanotechnology is still in a formative phase--not unlike the condition of computer science in the 1960s or biotechnology in the 1980s. Yet it is maturing rapidly. Between 1997 and 2005, investment in nanotech research and development by governments around the world soared from $432 million to about $4.1 billion, and corresponding industry investment exceeded that of governments by 2005. By 2015, products incorporating nanotech will contribute approximately $1 trillion to the global economy. About two million workers will be employed in nanotech industries, and three times that many will have supporting jobsnanotechnology

11. Nanotechnology as an industry has crept into several other major industry topics covered by BCC Research. The innovation and emerging nanotechnologies have significantly reshaped the manufacturing, biotechnology, environmental and pharmaceutical markets. Nanoparticles, nanotubes, nanocomposites and nanoclays are all covered within BCC Research reports. In-depth market analysis of these technologies as well as trends, forecasts and profiles of major players prove how valuable the growth of nanotechnology has become. Efficiency of nanotechnology has led to great discoveries in prescription drug products, photonics and has had a great environmental impact in the water treatment and decreasing the amount of pollutants that deplete the environment.

12. The Project of Emerging Nanotechnologies  Consumer Products  An inventory of nanotechnology-based  consumer products currently on the market  After more than twenty years of basic and applied research, nanotechnologies are gaining in commercial use. Nanoscale materials now are in electronic, cosmetics, automotive and medical products. But it has been difficult to find out how many “nano” consumer products are on the market and which merchandise could be called “nano.”  While not comprehensive, this inventory gives the public the best available look at the 1,000+ manufacturer- identified nanotechnology-based consumer products currently on the market.

13. Products with Nanotechnology  You might be surprised to find out how many products on the market are already benefiting from nanotechnology.  Sunscreen - Many sunscreens contain nanoparticles of zinc oxide or titanium oxide. Older sunscreen formulas use larger particles, which is what gives most sunscreens their whitish color. Smaller particles are less visible, meaning that when you rub the sunscreen into your skin, it doesn't give you a whitish tinge.Sunscreen
