New ‘Nano-skin’ = Super bendy screens

A flexible polymer infused with billions of carbon nanotubes could be used to make incredibly bendy displays and other novel electronic devices, researchers say.

The “nano-skin” polymer was created by scientists at Rensselaer Polytechnic Institute (RPI) in New York, US. Nanotubes are excellent electrical conductors and group member Swastik Kar says the material may well be used to build highly efficient electronic parts for highly flexible electronic displays.

Nano-battery to power artificial retina

nanobattery.jpgThe center will design, model, synthesize, and fabricate nanomedical devices based on natural and synthetic ion transporters — proteins that control ion motion across the membranes of every living cell.

The first task for the center will be to design a class of devices for generating electric power — bio-batteries — for a wide array of implantable devices, starting with an artificial retina that has already been developed at the Doheny Eye Institute at the University of Southern California. The artificial retina and accompanying nanobattery will be used to correct certain types of macular degeneration.

Inching ever so closer to a world filled with Mek.

Nano-Armor a reality and tougher than all get-out

An Israeli firm has developed armor based on nanotechnology.

ApNano has tested armor said to be five times stronger than steel and twice as strong as any impact-resistant material used in protective gear.

Last year, a sample of the ApNano material was subjected to tests in which a steel projectile traveling at a speed of up to 1.5 kilometers per second slammed into the material.

Executives said the impact was the equivalent to dropping four diesel locomotives onto an area the size of a human fingernail.

They said the nano-based armor, which stemmed from a new carbon form called Inorganic Fullerenes, withstood the impact.

The company’s chief executive officer, Menachem Genut, said the company would launch initial production within the next six months. Genut said this would mean the production of between 100 and 200 kilograms of the nano-material per day.

Buckyballs may disrupt DNA

Computer simulations show that a common nanoparticle called a buckyball has the potential to damage DNA. The simulations suggest that buckyballs bind strongly to the DNA strands, distorting the molecules and interfering with functions like self-repair.

[…]

Buckyballs, or buckminsterfullerenes (C60), are hollow spheres made from 60 carbon atoms. Because of their unique physical properties they are being considered for many applications, from drug delivery to fuel cells.

Researchers at Oak Ridge National Laboratory in Tennessee, and Vanderbilt University in Nashville, both in the US, decided to investigate how buckyballs would react if they came into contact with DNA. They used standard biomolecular simulation software to model two strands of DNA, with 12 base pairs each, interacting with two buckyballs over about 20 nanoseconds.

They found that the buckyballs bind strongly to DNA, with about the same energy that drugs bind to receptors on the surface of cells. When the buckyballs bound, they distorted the strands of DNA. Peter Cummings, a Vanderbilt chemical engineer, says it seems likely the interaction would interfere with the DNA’s function, disrupting replication and repair and increasing mutation rates.

Scientists who watch too much Star Wars to Cure Cancer with Nanotech

It’s a space-opera scene we know by heart: The hero’s tiny craft faces off against the vast enemy ship. Now scale down the set a billion times or so, and replace Luke Skywalker’s X-wing and the Death Star with a clump of drug-bearing molecules and a misshapen cancer cell.

Ka-BOOM!

This scenario — from a National Cancer Institute video — is just one possibility offered by the burgeoning field of cancer nanotechnology, where miniscule molecules are designed with literally atomic precision to combat a disease that kills half a million Americans every year.

“It’s 21st-century medicine,” said Vicki Colvin of Rice University’s Center for Nanoscale Science and Technology. “It sits at the intersection of some of the greatest achievements in many different areas of science, from material science to cell biology to physics and advances in imaging.”

Indeed, the National Cancer Institute, which recently announced two waves of funding for nanotech training and research, sees nanotechnology as vital to its stated goal of “eliminating suffering and death from cancer by 2015.”

Light Moves a Blob(of Liquid)
Edinburgh scientists have made a small blob of liquid move across a surface by shining a light in front of it.

[…]

The team envisages this technology moving biological samples around a diagnostic chip to detect disease.

The researchers can also see their work leading to smart materials that change their shape at the flick of a switch.

Fine Tuning the art of the “Bamf”

More teleportation news:

In the future it might be possible to assemble spacecraft “on-the-spot” using local materials. “That would be a further step along the road to true teleportation,” Darling added.

Taking this idea to its logical endpoint is when nanotechnology enters the scene, Darling said.

When nanotechnology is mature, an automated assembly unit could be sent to a destination. On arrival, it would build the required robot explorer from the molecular level up.

“Bona fide quantum teleportation, as applied to space travel, would mean sending a supply of entangled particles to the target world, then use what Einstein called ‘spooky action at a distance’ to make these particles assume the exact state of another collection of entangled particles back on Earth,” Darling speculated.

Doing so opens the prospect for genuinely teleporting a robot vehicle — or even an entire human crew — across interplanetary or, in the long run, across interstellar distances, Darling said.

“Certainly, if it becomes possible to teleport humans,” Darling said, “you can envisage people hopping to the moon or to other parts of the solar system, as quickly and as easily as we move data around the Internet today.”

Jack-in and control your world

Wild interview with bioethicist Paul Wolpe about tech that’ll let you use your mind to control computers.

But in terms of what most people mean by brain-computer interfaces, there?s a lot of work being done to create noninvasive BCIs by putting electrodes on people?s scalps or having them wear these caps that are infiltrated with sensors. The goal is a system that could retrieve much more detailed and specific information from the brain so that people could do sophisticated kinds of work through thought alone. It?s very promising for people who are paralyzed, but it also means that I could sit here at my computer with a cap on my head and answer the phone, ?type? on my computer, be connected to my colleague in the office next door?through brain impulses alone. That?s one area I think technology may take us over the next 50 or 60 years. We?re going to be able to manipulate any system that has a sophisticated chip in it, everything from your wristwatch to your car.

Cancer Institute Starts Nanotechnology Drive

The $144.5 million plan will include the NCI Alliance for Nanotechnology in Cancer, an initiative to team up researchers, physicians, companies and not-for-profit groups to develop nanotechnology products for use in diagnosing and treating cancer.

Medicine already employs molecular size devices in the shape of natural and artificially engineered proteins such as antibodies. “What’s new is we can build new nano-objects that never existed before,” Smalley said.

These can be coated with homing devices such as antibodies, artificial or natural, that will find cancerous cells. They could also carry drugs to kill the cells or imaging agents to help detect cancer, said Dr. Mauro Ferrari, a special adviser to the NCI and a professor of biomedical engineering at Ohio State University.
