Nanoparticles created to seek out cancer cells

Moscow - A key application of nanotechnology is in the medical field and one useful application is with the early detection of cancerous cells. Researchers from Russia report on a new innovation.

Next-gen carbon monoxide sensors based on nanotech

The monitoring of air, especially in homes and workplaces, for carbon monoxide is a critical part of health and safety. Early detection is key to lowering risks of poisoning. To improve current technology, Japanese researchers are looking to nanotech.

New battery can be recharged up to 200,000 times

Irvine - Researchers at the University of California Irvine have developed a nanowire-based battery material that can recharged several hundred thousand times without breakdown or loss of energy.

Using nanoparticles to block asthma

A biodegradable nanoparticle has been used to treat asthma and other allergies in a radically different type of research. The particles act in a way to stop the immune system from attacking an allergen and thus preventing the allergic response.

Potential prostate cancer treatment announced

A new therapeutic drug for the treatment of prostate cancer has been trialed, and shown to be effective. The drug inhibits a protein known to contribute to the disease.

Cancer battling nanoparticle method devised

A means of combating aggressive breast cancer with a drug based on nanotechnology has been developed. In animal trials, metastatic cancer was successfully treated, paving the way for human trials.

Nanoparticle delivery system to tackle cancer

Directing drug treatment to tumors is a hit-or-miss activity. Considerable research efforts are going into improving targeted drug delivery. A new approach centers on nanotechnology.

Bubble pen paves the way for improved technology

Austin - Scientists have created a "bubble pen," and the technique of bubble-pen lithography, to inscribe nanoparticles onto a surface.

Bones self-repair thanks to nanotechnology

University of Michigan researchers have created a polymer sphere capable of delivering a molecule directly into bone wounds. The molecule instructs cells at the injury site to repair the damage.

Nanotechnology creates new, super strong magnesium

Scientists have invented a new, super-strong and structurally light metal that possess extremely high specific strength.

Catch the dust, real gold as light as air

Zurich - A new type of gold has been created and it is as light as air. The new material takes the form of a foam and it is one thousand times lighter than mined gold, making the material the lightest form of the metal ever produced.

New method for treating pancreatic cancer

Oxford - Scientists may have found a new method for treating pancreatic cancer, and one which could lead to improved survival rates. The research is, so far, based on animal models.

New super glue only becomes sticky when crushed

Researchers in Japan have invented a new type of glue that is dry and non-sticky until it is crushed. Once broken up the substance acts like any other adhesive.

Nanoparticles used to boost tomato growth

Food scientists are keen to find ways to boost food production, and one way to create novel foods is through the use of nanotechnology. One area under review is tomatoes.

Super-thin graphene developed for next gen devices

Swinburne University of Technology scientists have developed an even thinner form of graphene in preparation for next-generation devices, including nano-scale surgery.

Making better batteries with nano-mechanics

As consumer electronics become ever more demanding in terms of power consumption, the hunt for new and improved batteries continues. Does nano-mechanics hold the answer?

Keeping underwater surfaces dry

Can a surface remain dry underwater for several months on end? A group of scientists and engineers think so, and they believe their surface has many commercial applications.

Seek, locate, destroy — Nanotech cleans up blood clots

Melbourne - Scientists have used nanoparticles to eliminate blood clots in the form of a field kit to be carried by medics on reaching the scene of a suspected heart attack or stroke case.

Super carbon filters play music in the heat

Detroit - Technologists have developed a carbon nanotube transducer with a special property: the device makes sounds, and plays music, with heat. The device is also light weight and portable.

Studying ants for clues about ultra-fine cleaning

Blue-sky thinking researchers have taken inspiration from the way that ants clean to develop improved procedures for nanotechnology. The ants studied are located in Borneo, Indonesia.

Using nanotechnology to treat diseases

Researchers are developing nanoparticles to direct drugs to specific places in the human body so that organs can be treated effectively. Many of these innovations can slowly release medications over a prolonged period of time.

New treatment for acne is effective

Washington - The slow release of nitric oxide, through nanotechnology, can be an effective cure against acne, according to new research. The nitric oxide tackles the bacteria that cause the spots and pimples on the skin to flare up.

Gene therapy destroys brain cancer in new study

Technologists have developed a nanoparticle transport system for gene delivery. The system can wipe out brain gliomas, which cause a deadly form of cancer.

Nanotech can tell you when it's time to change your car’s oil

When to change out engine oil is a dilemma that many car drivers face (or for the less practically minded, when to ask the garage to do it). A new nanotech invention can give motorists the answer.

Halting cancer in its tracks, with nanotechnology

Most cancer therapies are focused on blasting a general area with radiation or using chemotherapy drugs to zoom in on a tumor site. Researchers using nanoparticles have taken a different tract, in trying to slow tumor growth through nanotech.

Programmable robots can swim through arteries

Researchers have developed tiny robots (‘nanobots’) that can swim through clogged arteries, carrying out lifesaving medical procedures.

Killing cancer with nanotechnology

On theory about killing cancer is that heat can be effective. Using this principle, a science group have begun trials on using nanoparticles and heat to attack tumors.

Using robots to search for new antibiotics

Roskilde - The search for new antibiotics is a matter of global importance. To help with the research for new compounds, scientists have created two robotic chemical-synthesizing machines.

Roll over biology, super computer creates better crops

For years biologists have toiled away to find ways to make better crops. Now it seems the answer lies with computers. An advanced computer has fully detailed the nanostructure of cellulose, the key to creating more robust grains.

Nanotech drug holds promise for treating Parkinson’s

A new method, employing nanotechnology, has shown promise for treating Parkinson’s disease. This is based on experiments using rats, although the results are promising enough to suggest that the method could one day see the drug used on people.
