Nanotechnology
Nanotechnology ("nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold.

What is Nanotechnology? The Meaning of Nanotechnology 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 few nanometers wide—motors, robot arms, and even whole computers, far smaller than a cell. Outline of nanotechnology Nanotechnology – study of physical phenomena on the nanoscale, dealing with things measured in nanometres, billionths of a meter. Nanotechnology is a complex scientific area involving the rearrangement of atoms at a molecular level, i.e. creating devices at a molecular level.[1] Atomic rearrangement depends on the material used because any alteration of the atoms changes the identity of the material. Nanotechnology is rearranging atoms to create things at an extremely small scale, and it was popularized by Eric Drexler: "Eric Drexler was the godfather of nanotechnology

Biotechnology "Bioscience" redirects here. For the scientific journal, see BioScience. For life sciences generally, see life science. Biotechnology is the use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity, Art. 2).[1] Depending on the tools and applications, it often overlaps with the (related) fields of bioengineering, biomedical engineering, etc. For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine.[2] The term is largely believed to have been coined in 1919 by Hungarian engineer Károly Ereky. In the late 20th and early 21st century, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene techniques, applied immunology, and development of pharmaceutical therapies and diagnostic tests.[2]

Nanotechnology Just give me the FAQ The next few paragraphs provide a brief introduction to the core concepts of nanotechnology, followed by links to further reading. Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. DNA brings materials to life: DNA-coated colloids help create novel self-assembling materials A colloid is a substance spread out evenly inside another substance. Everyday examples include milk, styrofoam, hair sprays, paints, shaving foam, gels and even dust, mud and fog. One of the most interesting properties of colloids is their ability to self-assemble -- to aggregate spontaneously into well-defined structures, driven by nothing but local interactions between the colloid's particles. Self-assembly has been of major interest in industry, since controlling it would open up a whole host of new technologies, such as smart drug-delivery patches or novel paints that change with light. In a recent Nature Communications publication, scientists from EPFL and the University of Cambridge have discovered a technique to control and direct the self-assembly of two different colloids.

Microelectromechanical systems Proposal submitted to DARPA in 1986 first introducing the term "microelectromechanical systems" Microelectromechanical systems (MEMS) (also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems and the related micromechatronics) is the technology of very small devices; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines (in Japan), or micro systems technology – MST (in Europe). MEMS are separate and distinct from the hypothetical vision of molecular nanotechnology or molecular electronics. MEMS are made up of components between 1 to 100 micrometres in size (i.e. 0.001 to 0.1 mm), and MEMS devices generally range in size from 20 micrometres (20 millionths of a metre) to a millimetre (i.e. 0.02 to 1.0 mm).

Quick links Quantum technology Quantum technology is a new field of physics and engineering, which transitions some of the stranger features of quantum mechanics, especially quantum entanglement and most recently quantum tunneling, into practical applications such as quantum computing, quantum cryptography, quantum simulation, quantum metrology, quantum sensing, and quantum imaging. The field of quantum technology was first outlined in a 1997 book by Gerard J. Milburn,[1] which was then followed by a 2003 article by Jonathan P. Dowling and Gerard J.

Nanotechnology is coming by Ralph C. Merkle, Principal Fellow, Zyvex This is the English original of an article translated into German and published in the Frankfurter Allgemeine Zeitung of Monday, September 11 2000 on page 55. In the coming decades nanotechnology could make a supercomputer so small it could barely be seen in a light microscope. Easy and effective therapy to restore sight: Engineered virus will improve gene therapy for blinding eye diseases Researchers at UC Berkeley have developed an easier and more effective method for inserting genes into eye cells that could greatly expand gene therapy to help restore sight to patients with blinding diseases ranging from inherited defects like retinitis pigmentosa to degenerative illnesses of old age, such as macular degeneration. Unlike current treatments, the new procedure is quick and surgically non-invasive, and it delivers normal genes to hard-to-reach cells throughout the entire retina. Over the last six years, several groups have successfully treated people with a rare inherited eye disease by injecting a virus with a normal gene directly into the retina of an eye with a defective gene. Despite the invasive process, the virus with the normal gene was not capable of reaching all the retinal cells that needed fixing.

Flip chip Process steps[edit] Comparison of mounting technologies[edit] Wire bonding/Thermosonic bonding[edit] The interconnections in a power package are made using thick aluminium wires (250 to 400 µm) wedge-bonded In typical semiconductor fabrication systems chips are built up in large numbers on a single large wafer of semiconductor material, typically silicon. The individual chips are patterned with small pads of metal near their edges that serve as the connections to an eventual mechanical carrier.

NANOTECHNOLOGY LAW BLOG 24/03/08 DuPont and ED Will Hold Nano Risk Management Training Workshops DuPont and Environmental Defense (ED) will hold two interactive workshops on nano risk management. The workshops are intended to give participants the tools they need to: Understand (and explain to others) why nano-specific risk management is necessary; Assemble and leverage the internal and external resources to implement nano-specific risk management; and Begin implementing nano-specific risk management in an efficient and effective manner. The workshops will include: Interactive discussions of how to implement nano-specific risk management; Case studies of nano-specific risk management in use by companies and governments; and Sources of additional help for companies adopting these approaches.

Programmable matter History[edit] In the early 1990s, there was a significant amount of work in reconfigurable modular robotics with a philosophy similar to programmable matter.[2] As semiconductor technology, nanotechnology, and self-replicating machine technology have advanced, the use of the term programmable matter has changed to reflect the fact that it is possible to build an ensemble of elements which can be "programmed" to change their physical properties in reality, not just in simulation.
