Nanotechnology has been touted as the next revolution in many industries, with more than 300 nanoproducts already on the market. Because of their size and increased surface area, nanoparticles are more reactive and have higher toxicity than they do in their normal form, and no government agency is regulating these particles. action.foodandwaterwatch.org/p/dia/action/public/?action_KEY=7566
17-year-old wins 100k for creating cancer-killing nanoparticle Dec. 8, 2011
Angela Zhang is, and she’s just been awarded the $100,000 Grand Prize in the Individual category of the Siemens Competition in Math, Science & Technology. Her project was entitled “Design of Image-guided, Photo-thermal Controlled Drug Releasing Multifunctional Nanosystem for the Treatment of Cancer Stem Cells.”
Her creation is being heralded as a “Swiss army knife of cancer treatment.” Zhang managed to develop a nanoparticle that can be delivered to the site of a tumor through the drug salinomycin. Once there it kills the cancer stem cells. However, Zhang went further and included both gold and iron-oxide components, which allow for non-invasive imaging of the site through MRI and Photoacoustics.
New microtweezers may build tiny 'MEMS' structures January 17, 2012
WEST LAFAYETTE, Ind. - Researchers have created new "microtweezers" capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research.
This 3D-printed model of the Tower Bridge is only 200 micrometers long. To put that into perspective, the distance between the towers is the width of a human hair. This model is the product of research at the additive manufacturing department of the Vienna University of Technology
The models were fabricated much like normal stereolithography – a laser shines onto a vat of light-sensitive resin. The resin hardens when exposed to light, and the model is built up layer by layer. These nanoscale models were made using a process called “two-photon lithography,” something we’re not going to pretend we understand completely but here’s a nice paper that provides a good overview. Needless to say, the precision these prints exhibit are nearly ludicrous. The researchers claim a precision of ±1µm, a respectable amount of precision for very high-tech machining applications.
Nano scientist collaboration with the US military could ramp up nano arms race
As 33 Australian nanotechnology scientists attend a 4 day workshop [Can Australian researchers help maintain the technological superiority of the US Air Force? www.scienceinpublic.com.au/media-releases/ausresearchinusairforce in Washington DC] to explore opportunities for collaboration with the US military, Friends of the Earth have raised concerns that collaboration could contribute to a nano arms race, making the world a much less safe place.
Dr Gregory Crocetti from Friends of the Earth Nanotechnology Project said “This is an obvious move by the United States to extend its military dominance into the Asia-Pacific region.”
“The US is understood to be making the world’s largest investment in military applications of nanotechnology – accounting for as much as 90% of global nano-military R&D. Why are Australian nanotechnology researchers getting into bed with the biggest war machine on the planet?”
“The US Government spends hundreds of millions of dollars each year on military nanotechnology R&D, with applications including explosives, surveillance and lasers. However, since most of the research is classified it is not clear exactly what research is going on.”
A 2005 NATO [179 STCMT 05 E - THE SECURITY IMPLICATIONS OF NANOTECHNOLOGY www.nato-pa.int/default.asp?SHORTCUT=677 ] report raised concerns that nanotechnology will permit chemical and biological warfare to become more feasible and effective, proliferation easier and that arms races are to be expected.
The Facility [Australian National Fabrication Facility (ANFF)], with hubs in NSW, Vic, Qld, SA and WA, gives researchers access to the tools to make their inventions. And they’ve been drawn like flies. Nineteen universities and CSIRO are partners in the Facility.
The US delegation includes representatives of: Department of State; Office of the Secretary of Defense; Air Force Office of Scientific Research; NASA; Army Research Laboratory; Naval Research Laboratory; DARPA; National Institutes of Health; and the National Science Foundation. Organized by US Air Force Office of Scientific Research.
In a bid to blast the clouds out of the sky for the Beijing Olympics last year, China's Weather Modification Office seeded clouds with chemicals. This Summer at the Design Interactions (RCA) graduation show, Zoe Papadopoulou and Cat Kramer proposed a much bolder and poetical take on the cloud seeding technology.
Cloud seeding with bacteria to make rain snow ice cream
As scientist and emerging technologies advisor Andrew Maynard wrote on his blog, the gap between the designers' concept and the current state of nanotechnology research is still fairly large. What was read instead was the group of experts lined up to give talks and discuss with the public in the ice cream van. Ice cream was in fact the bait that lured passersby into having conversations about nanotechnology, geoengineering and emerging technologies in general.
(Nanowerk Spotlight) New research explores the uses of time reversal symmetry in optics, with a focus on quantum optics. "Time reversal symmetry in optics" in Physica Scripta is authored by Gerd Leuchs and Markus Sondermann, both affiliated with the University of Erlangen-Nuremberg and the Max Planck Institute for the Science of Light in Erlangen, Germany. The article compares time reversal with optical phase conjugation, and illustrates the concept of time reversal symmetry with several examples in classical and quantum optics.

Study: Popular Nanoparticle Causes Toxicity In Fish; 'There Is Reason To Be Concerned' March 2, 2010 17:10 EST
[...] Sepúlveda and doctoral student Geoff Laban exposed fathead minnows to nanosilver at several stages of their development, from embryo to the point where they swim up from the bottom of their habitats to eat for the first time. Even without sonication, nanosilver caused malformations that included head hemorrhages and edema, and ultimately proved lethal.
[...] Nanosilver is growing in popularity as a component of many products. It is used to kill bacteria in goods such as odor-control clothing, countertops, cutting boards and detergents. Currently, there are few regulations for nanosilver's applications in products, but Ron Turco, professor of agronomy and the paper's co-author, said the Environmental Protection Agency is reviewing the situation.
Turco also indicated there has been little work done to estimate the current level of nanosilver being released into the environment.
"Silver has been used in the past as an antimicrobial agent. It's a known toxicant to microorganisms," he said. "Nanosilver is being considered by the EPA for environmental exposure profiling, much like a pesticide."
I am interested in molecular manufacturing (also called molecular nanotechnology, see my video introduction). The central objective of molecular manufacturing is the design, modeling, and manufacture of systems that can inexpensively fabricate most products that can be specified in molecular detail. This would include, for example, molecular logic elements connected in complex patterns to form molecular computers, molecular robotic arms or Stewart platforms (e.g., positional devices) able to position individual atoms or clusters of atoms under programmatic control (useful if we wish too make molecular computers and other molecular manufacturing systems), and a wide range of other molecular devices. A central concept for achieving low cost in molecular manufacturing is that of massive parallelism, either by self replicating manufacturing systems or convergent assembly. Such systems are today theoretical, but should revolutionize 21st century manufacturing. The marginal manufacturing costs for such systems should be quite small, although initial R&D costs might be quite high. I served for several years as an executive editor of the journal Nanotechnology. I chaired both the Fourth and Fifth Foresight Conferences on Molecular Nanotechnology; and won the 1998 Feynman Prize in Nanotechnology for theory. Robert Freitas and I have formed the Nanofactory Collaboration.
I also have a broad interest in computer security and a particular interest in cryptography, having co-invented public key cryptography (for which I received the ACM Kanellakis Award, the IEEE Kobayashi Award, the RSA Award in Mathematics, the IEEE Hamming Medal (see Stanford's article), was inducted into the National Inventors Hall of Fame, and was named an IACR Fellow). I also invented Merkle trees. A C program that implements a digital signature using Merkle trees is available. See Handbook of Applied Cryptography for an excellent technical treatment of cryptographic methods, and Crypto for a great read about the people involved. My first paper on public key cryptography in 1974 was rejected by an unknown "cryptography expert" because it was "...not in the main stream of present cryptography thinking...."
Does nanotechnology offer athletes more than a sporting chance? Tuesday 8 May 2012 18.20 BST
Such was the case with Speedo's LZR Racer bodysuit, worn by more than 90% of the gold medal swimmers at the Beijing Olympics in 2008. The suit, the fabric of which is coated with water-repellent nanoparticles and incorporates polyurethane panels, traps air and compresses the body to increase buoyancy of the swimmer and reduce drag.
After 168 world records were broken by competitive swimmers wearing such suits, Fina (Federation Internationale de Natation), the sport's international governing body, banned "non-textile" suits in 2010 for being a technical aid that give competitors an unfair advantage – so-called "technology doping".
Nanomaterial to store ‘future fuel’ The University of New South Wales Thursday, 16 August 2012 davidf_-_hydrogen Hydrogen, considered a major fuel of the future, could be used to power buildings, portable electronics and vehicles. Image: davidf/iStockphoto
For the first time, engineers at the University of New South Wales have demonstrated that hydrogen can be released and reabsorbed from a promising storage material, overcoming a major hurdle to its use as an alternative fuel source.
Researchers from the Materials Energy Research Laboratory in nanoscale (MERLin) at UNSW have synthesised nanoparticles of a commonly overlooked chemical compound called sodium borohydride and encased these inside nickel shells.
"Bioengineers at Harvard University have created the first examples of cyborg tissue: Neurons, heart cells, muscle, and blood vessels that are interwoven by nanowires and transistors. These cyborg tissues are half living cells, half electronics. As far as the cells are concerned, they're just normal cells that behave normally — but the electronic side actually acts as a sensor network, allowing a computer to interface directly with the cells. In the case of cyborg heart tissue, the researchers have already used the embedded nanowires to measure the contractions (heart rate) of the cells. So far, the researchers have only used the nanoelectric scaffolds to read data from the cells — but according to lead researcher Charles Lieber, the next step is to find a way of talking to the individual cells, to 'wire up tissue and communicate with it in the same way a biological system does.' Suffice it to say, if you can use a digital computer to read and write data to your body's cells, there are some awesome applications." slashdot.org/index2.pl?fhfilter=biotech

Nanoparticles slow trout down
20 November 2012, by Tom Marshall
Exposure to man-made titanium dioxide nanoparticles means trout spend less time swimming at top speed, scientists have shown. They think the particles damage the fish's gills, causing oxygen deprivation in the internal organs including the brain and forcing them to save energy by cutting out rapid bursts of movement. Rainbow trout
The changes won't have much impact on the animals' activity most of the time, but affected trout may struggle to put on the sudden bursts of speed that might be needed to flee a predator, fight a rival for the chance to mate or catch elusive prey. planetearth.nerc.ac.uk/news/story.aspx?id=1293
