Nanotechnology: Frequently Asked Questions
What is nanotechnology?
Nanotechnology: science and practical technology of manipulating matter at molecular and atomic scale with a high processivity. I would actually avoid the term nanotechnology, since tainted, and consistently use 'molecular manufacturing' instead.

The definition most frequently used by government and industry involves structures, devices, and systems having novel properties and functions due to the arrangement of their atoms on the 1 to 100 nanometer scale. Many fields of endeavor contribute to nanotechnology, including molecular physics, materials science, chemistry, biology, computer science, electrical engineering, and mechanical engineering. Due to the extreme breadth and generality of this definition, many prefer to use the term "nanotechnologies. ...

The term nano comes from a Greek word meaning dwarf. Nanotechnology is science and engineering at the scale of atoms and molecules. It is the manipulation and use of materials and devices so tiny that nothing can be built any smaller. Materials at the nanoscale are typically between 0.1 and 100 nanometres (nm) in size - 1 nm is one billionth of a metre (10 -9 m). ...

Nanotechnology is the science of designing and building on the atomic or molecular level. The nanoscale is one billionth of a meter-80,000 times smaller than the width of a human hair.

Is nanotechnology dangerous?
It depends on whether you mean nanosized or nanostrucured. If large amounts of nanosized particles are emitted, it is dangerous to inhale since your lungs can be damaged. But there are already nanosized particles around us everywhere, for instance in car exhausts, and toner for copying machines or laser printers. However, a glass surface which is nanostructured to keep clean does not emit any nanoparticles.

Is Nanotechnology new?
No. Pottery using nano-sized particles has been used for thousands of years. An example from 4th Century AD is the Lycurgus Chalice and can be seen at the British Museum. The cup is made from glass which appears jade green in reflected light, but when light is shone directly through the glass it appears translucent red. This unusual optical effect is caused by 40ppm (parts per million) gold and 300ppm silver contained within the glass producing 70nm particles.

How is this nanotechnology?
Nanotechnology generally describes products and processes involving the manipulation of materials 1-100 nanometers across. (For example, a red blood cell is about 7,000 nanometers wide). Each cell, or bubble, in the Metcomb cellular metal is protected by an oxide skin which is derived from gas during the Inegrated Nanostructure Control process. This solid oxide skin is 10-90 nm thick and is critical to maintaining the stability of the cells.

What are nanotechnology and nanomedicine?
Molecular nanotechnology is an emerging technology for manufacturing and manipulating matter at the molecular level. The concept was first suggested by Richard Feynman in 1959. The theoretical foundations of molecular nanotechnology were developed by K. Eric Drexler, Ralph Merkle, and others in the 1980s and 1990s. ...

Are you "boosters" for nanotechnology?
We are boosters for safe use of nanotechnology. CRN promotes research into molecular manufacturing not
in spite of the risks, but
because of the risks. Only through exploration, understanding, and education can we hope to make good decisions about developing and administering this transformative technology.

Why fund nanotechnology?
Because of the promise of nanotechnology to improve lives and to contribute to economic growth, the Federal Government, through the guiding efforts of the U.S. National Nanotechnology Initiative (NNI), is supporting research in nanotechnology. As a result of the NNI research efforts, the United States is a global leader in nanotechnology development.

Nanotechnology has the potential to profoundly change our economy and to improve our standard of living, in a manner not unlike the impact made by advances over the past two decades by information technology. While commercial products are starting to come to market, some of the major applications for nanotechnology are five to ten years out. Private investors look for shorter-term returns on investment, more in the range of one to three years. ...

Why is nanotechnology interesting?
In the nano dimension there are physical phenomena which are of interest to study and use in new applications. The nanoparticle surface to volume ratio is much larger for instance. Some things which we learnt in school are no longer true, such as Ohm's law (voltage = current x resistance). Other examples are that non-magnetic metals can have magnetic properties and that gold appears green.

What is Nanoscience/Nanotechnology?
Nanoscience is defined as ‘the study of phenomena and manipulation of materials’ at the nanoscale – research which will fuel technology advances in the future. Nanotechnology is the design, characterisation, production and application of structures, devices and systems at the nanometre scale.

Why develop nanotechnology?
Gaining better control over the structure of matter has been a primary project of our species since we started chipping flint. The quality of all human-made goods depends on the arrangement of their atoms. The cost of our products depends on how difficult it is for us to get the atoms and molecules to connect up the way we want them. The amount of energy used - and pollution created - depends on the methods we use to place and connect the molecules into a given product. ...

Which country leads in nanotechnology?
World leadership in nanotechnology varies according to which sub-category of technology is being examined. In general, nanotechnology is unlike a number of recent major technological innovations in that the U.S. does not hold a very strong lead at the start. High quality work is taking place around the world, including countries with a higher fraction of engineering graduates, much lower R&D; costs, and (unfortunately) less-stringent environmental standards.

When is nanotechnology going to happen?
Obviously only guesses can be made. It also depends on what one considers the defining moment for nanotechnology. At the current time estimates quoted in the usenet group range from 5 to 150 years for the first working devices of nanotech dimensions. Dates for actual assemblers range from 50 to 200 years. {AJ}

What is the current state of nanotechnology?
The field of nanotechnology is so wide and currently undergoing a period of expansion that any answer to this question is sure to be outstripped quickly. The Nanotechnology Opportunity Report as of November 2001 is the best and most up to date overview and development map of the state of fairly recent activities. For an older perspectives there is the WTEC reports from early 2001. We are keeping a record of the current development state of the Universal Assembler .
