NanoTechology
(Nanorobotics - Wikipedia) is Technology build on a atomic or sub-atomic scale, that is
built form atoms. Many be known as Nanites,
Nanoagents, and Nanorobots They have dimensions of a few nanometers (nm) or
less. Where 1 nm = 110−9 m (engineering notation) or 1 E-9 m (exponential notation). Meaning 1/1,000,000,000
metres.

Most people in the world know exactly how long a kilometer is, how large a liter is, how much a kilogram weighs, and how warm 25C is. That's because almost all countries in the world have adopted a standard called the metric system - since the 1960s the International System of Units has been the internationally recognized standard system for measurements (only three countries have not adopted this standard: Liberia, Myanmar, and the United States - the latter maybe because the metric system was invented by the French...). The need for standardization also exists in various fields of nanotechnology in order to support commercialization and market development, provide a basis for procurement, and support appropriate legislation/regulation. When it comes to nanotechnology, numerous standard setting organizations around the world are active in defining nanotechnology standards, although no one standard has achieved dominance yet.

The phenomenon behind many color-based biosensor applications is the excitation of surface plasmons by light - called surface plasmon resonance for planar surfaces or localized surface plasmon resonance (LSPR) for nanoscale metallic structures. Surface plasmon resonance of metallic nanoparticles, in particular gold, has become a popular nanotechnology-enabled technique to build increasingly sensitive and fast biosensors. All the nanostructures used for the biosensing applications have two characteristics: Firstly, they contain certain recognition mechanisms specified to the analyte, for example antibodies or enzymes. Secondly, they are able to generate a distinguishing signal from the analyte and this signal could be generated by the nanostructures themselves or produced by signaling molecules immobilized or contained in the nanostructures. However, proper functionalization remains an issue when it comes to real-world applications, in particular, biological relevant samples such as membrane associated proteins and peptides.

For a decade, researchers and industry professionals have been warning that the limits of silicon were quickly being approached. According to some, these limits have, effectively, already been reached. The age of the integrated microchip circuit - fabricated out of silicon - may be drawing to a close. But, is there any technology ready to fill the void? Is there any technology that could make circuits smaller or more powerful? They answer to this may very well be 'yes.' Although silicon holds numerous properties that make it a rather ideal conductor of electricity under certain conditions, it lacks one crucial characteristic, which may end-up making carbon the material of the future: The ability to form complex, tubular arrays on the scale of only a few nanometers. The age of the integrated nanochip circuit - made-up of composite carbon nanotubes - may have arrived.

Don't you just love the "for dummies" series? I hope the title doesn't personally offend anyone. I'm not calling anyone a dummy. I just like the book series.
So, have you read Nanotechnology for Dummies? This book is great because it breaks down the science into a simple, yet meaningful explanation. Many people have misconceptions about what nanotechnology is about. Some think that nanotechnology is just about microscopic robots. Others think that nanotechnology only applies to microchips and computer technology.
It's easy reading and also serves as a nice gift if you're ever in need of one. Visit Dummies.com to see all the other "for dummies" books.

What does it mean to be a nanotechnology expert? Have you ever wondered what type of education would be required? The application of nanotechnology spans across all industries. For instance, healthcare is a huge area where nanotechnology is revolutionizing the medical management of diseases and ailments. The electronics industry would be transformed if nanotechnology research brings forth batteries that have 10 times the power as existing rechargeable batteries.
I advise many high school students who are in the process of applying to college. Some have recently expressed their interest in nanotechnology and science. What major should this student select? Biomedical engineering? Materials science? Mathematics? Mechanical engineering? Chemistry? Physics? Cellular biology? The choices seem endless. Some colleges have a major called "nanoscience." The University of Guelph is the first to offer this major in Canada. What about "nano-engineering?" I wouldn't be surprised if these majors start popping up in the future. Perhaps they won't catch on for undergraduate degrees, but I can certainly see this happening for graduate studies.

Have you ever tried to use tape on a wet surface? It doesn't stick, does it? Scientists are finding so many incredible discoveries in nature. Researchers at MIT may be on the verge of discovering something never novel - a waterproof adhesive bandage that may close surgical wounds. They are getting their inspiration by looking at how geckos use their sticky feet to climb walls and even hang upside down. The adhesive is being designed using nanotechnology to build pillars and a sticky glue-like substance.
Geckos have very sticky feet, but they can also lift their feet very easily. This new adhesive is being designed to be more permanent. Can you imagine using a bandage that has an adhesive that will stick to any type of wet surface?
Isn't this great? Scientists are using nanotechnology to create a new type of adhesive. Over the last decade, we've seen new bandages and glues used to close wounds. Soldiers on the battlefield now have access to revolutionary wound closure systems. To read more about this new adhesive technology, visit the MIT news office.

In the past, nanostructured materials have been used to create an invisibility cloak that works in the microwave portion of the spectrum. Now, for the first time, team led by Igor Smolyaninov at the University of Maryland has used surface plasmonics and nanostructured materials to make an invisibility cloak that works in the visible light range - but only at a scale of microns, and in only two dimensions - for now.
My opinion is that this is an amazing advance. Along with the plastic as strong as steel, this really shows that nanostructured materials are making serious progress. It's just a matter of time before these are integrated into consumer products with properties that seem almost "magical" from the viewpoint of present-day consumers.

Researchers at Rensselaer Polytechnic Institute have created tiny nanoblades made out of magnesium. They used oblique angle deposition, which was previously thought to always create cylindrical structures like nanorods or nanosprings.
These blades are practically two-dimensional, with a thickness of only 15 nanometers. Now the researchers are looking for ways to coat these nanoblades with metallic catalysts so they can be used as high-density storage for hydrogen fuel cells.

The addition to quantum dots to solar cells could lead to a tripling in efficiency, boosting from the usual 10% up to 40% or 60% (with concentrators). Silicon nanocrystals (quantum dots) are able to extract two or three electrons for each incoming photon, an unprecedented feat. Although solar is often hailed as a great, environmentally friendly energy source, it has a ways to go before being able to compete with fossil fuels - but efforts like this could make the difference.

Scientists at Clemson University managed to extend the lifespan of florescent nanoparticles, which are used for all sorts of biomarking-related purposes. Because these nanoparticles are single molecules just about the site of a protein, they can be distributed pretty much everywhere in living tissue, penetrating into every nook and cranny. Now, they've even made a florescent nanoparticle so bright that you can put it inside a cell and it shines right through. Now that's a bright idea

Using a technique called selective laser sintering, researchers have discovered a method to produce components for scientific setups in a very fast and easy way. In the picture, we see an atomic force microscope head, a commonly used instrument in nanotechnology. Robert Lugmaier extensively compared conventionally manufacturing AFMs with laser sintered AFMs and found that both worked equally well, although the latter wore out faster. The lesser cost, however, makes all the difference. AFM heads typically cost tens of thousands of dollars.

Today, Mike Honda (D-San Jose) introduced HR 3235, the Nanotechnology Advancement and New Opportunities (NANO) Act, comprehensive legislation for nanotech development in the US. Mike Honda has been a long-time supporter of nanotechnology and I was fortunate to meet him in person at a Foresight Senior Associates Gathering in 2004, at which he gave a talk. A report, "Thinking Big About Thinking Small", was released concurrently by the Blue Ribbon Task force on Nanotechnology, a group of California industry experts who made a series of recommendations in the crafting of the bill. The United States is currently the world leader in nanotechnology research, but China, Russia, and the EU and spending billions to keep pace.

In an advance that sounds like something right out of science fiction, Ulf Leonhardt and Thomas Philbin of the University of St Andrews have determined that a perfect lens (something not created yet but technologically plausible) could reverse the normally attractive Casimir force, making it repulsive. The Casimir force is a non-classical physical effect whereby two neutral plates placed in close proximity slightly attract. The Casimir force is especially relevant to micromachines and nanomachines, where the effect is more pronounced. If it could be reversed, this would solve many of the stickiness problems associated with tiny machines.

Optical tweezers and plasmonics represent the light-based side of nanotechnology, where photons are used to perform useful tasks such as lab-on-a-chip functions and the mechanical manipulation of tiny objects like proteins. Plasmonics has garnered tremendous excitement in the last couple years, because of the way it can circumvent traditional size restrictions based on light wavelength. Eventually, plasmonics may be used to create optical nanocomputers millions of times faster than the best we have today. Optical tweezing technology won its inventor the 1997 Nobel Prize in Physics.

Researchers at the London Center for Nanotechnology have exploited a hidden magnetic "quantum order" which can be measured to determine the degree of coherence in small systems of atoms. The red peak in the image shows almost perfect quantum coherence. The material of study was a ceramic made up of nickel-centered oxygen octahedra. The researchers didn't' only image the quantum coherence, but manipulated the distance over which it was maintained by changing the temperature and using other elements for doping. Superconductivity and superfluidity are examples of phenomena where large-scale quantum phase coherence is observed.

In a technological advance that brings man and machine closer to each other, Zhong Lin Wang and colleagues at the Georgia Institute of Technology have built a nanogenerator that uses supersonic vibrations in blood to generate electricity. The power density of the generators approaches 4 W/cubic centimeter, which, if they could be made more cheaply, would open up a variety of applications, including biosensors and prosthetic implants. Running a scaled-down operating system like TinyOS, nanogenerator-powered bloodborne nanomachines will one day transform medicine, healing ailments without the need for surgery.

Japanese stationery and writing instrument manufacturer Pentel has invented a kind of pencil lead by combining together the skills and knowledge of aromatherapists with nanotechnologists. Utilizing nanocapsules, the lead is able to maintain a pleasant aroma for up to 2 years if kept in a package and 3 months if left in open air. Previous forms of scented lead only received surface treatment and lost their scent very quickly. This new product, "Ain supplio", recently won the Stationery of the Year Award (2007).

Scientists at the University of Southampton in the United Kingdom and the Deutsches Kunststoff-Institut (DKI) in Darmstadt, Germany have developed a new type of self-assembling polymer opal film, which can be used to make objects that change color when stretched. These polymer films are photonic crystals, made up of trillions of little spheres with holes between them similar to certain wavelengths of light. These holes preferentially reflect certain frequencies based on their precise size. Applications for the technology are still being thought up, but counterfeit prevention, smart materials, and food packaging have been proposed.

Electrochemists in the United States were able to create a syringe capable of injecting attoliter-sized quantities of fluid. An attoliter is a billion billionth of a liter, a volume of fluid equal to a cube 100 nm on a side. The pipette pictured is 150-nm on a side, shown injecting fluid into a single cell, without damaging the cell or causing it to change its behavior appreciably. Its inventors see applications for this attosyringe in cellular biology research.

The Nanofactory Collaboration project is a cooperative group started by molecular nanotechnology pioneers Dr. Ralph Merkle and Robert Freitas. The project's goal is to create reprogrammable, ~100nm-scale robotic arms and mills, some capable of self-replication, for use in a nanomanufacturing system scalable to the desktop level.
Their site answers the questions, "what is a nanofactory?", and "what is diamondoid", among others. Freitas and Merkle have been been joined by over a dozen collaborators, all working on different nanoscale systems. The Nanofactory Collaboration group is currently seeking additional researchers as well as corporate sponsors.

Using a special dye molecule, azobenzene, which is two benzene rings linked together, combined with an ultraviolet laser, Berkeley scientists were able to make molecular assemblies change shape at will. This can be seen as a version of proto-nanorobotics. Most current nanorobotics involves only one piece or switch - future assemblages may have hundreds, thousands, or even millions of individual components.

Berkeley scientists have succeeded in injecting a protein-coated quantum dot into a living human cell using a nanotube-tipped atomic force microscope. This is a unique milestone because it represents the first time that researchers have been able to mechanically penetrate a cell wall without damaging it, something a micropipette cannot do. In the near term, this technique will be useful for studying cell biology by injecting almost arbitrary molecules into the intracellular milieu. In the longer term, it could be used for nanomedicine.

The Nanorobotics Research Group, a technology project involving collaboration across five departments at five universities, including the University of Sheffield, Sheffield Hallam University, and Nottingham University, is having an open day and workshop in Sheffield next Monday. I hope some valuable insights and dialogue come out of it.
The Nanorobotics Research Group is interesting and important because it's actually engaged in intelligently-directed manipulations at the atomic scale, rather than hands-off self-assembly, nano-particle doping, exploiting various inherent properties of nanotubes, and the like. You might call it the difference between nanorobotics and nanotechnology in general. While all fields of nanotechnology are important, I believe that nanorobotics represents the long-term future of nanotechnology research.
