The main breakthrough of the project has been applying nanotechnology to coat key parts of the hydraulic system,

The project consortium focused on achieving this by combining three emerging technologies nanotechnology, optical technologies,

This is where advances in nanotechnology could provide solutions.''We were estimating the friction between teeth and the brackets braces,

and it occurred to us that nanotechnology might be of use to help us resolve this issue,

A grant from Johns Hopkins Institute for Nanobiotechnology and a National Cancer Institute grant supported the work.

There s no reason we can t grow extraordinarily large single crystals in the future using modifications of our techniquesays Mirkin who also is a professor of medicine chemical and biological engineering biomedical engineering and materials science and engineering and director of the university s International Institute for Nanotechnology.

The combination of these properties makes graphene an ideal material for nanoelectromechanical systems (NEMS) which are scaled-down versions of the microelectromechanical systems (MEMS) used widely for sensing of vibration and acceleration.

For example Hone explains MEMS sensors figure out how your smartphone or tablet is tilted to rotate the screen.

#Scientists find that exposure to nanoparticles could impact cardiovascular health Due to its huge potential in applications ranging from cheaper vaccinations to energy-storing car panels there's plenty of excitement surrounding the emergence of nanotechnology.

This study isn't the first time concerns have been raised about the dangers of nanotechnology. Operating at a scale of 1-100 nanometers (a nanometer is one billionth of a meter) the chemical reactions

when dealing with nanotechnology can be somewhat unpredictable. Previous research has turned up some unsettling results including that silver nanoparticles can materially alter a person's immunity and that titanium dioxide nanoparticles cause systemic genetic damage in mice.

The researchers warn that adopting a cautious approach is critical in the near-term with nanotechnology-based consumer products on the rise a world market they estimate will hit US$3 trillion by 2020.

Our approach reduces the cost of nanolithography to the point where it could be done in your garage says Dr. Chih-Hao Chang an assistant professor of mechanical and aerospace engineering at NC State and senior author of a paper on the work.

The nanospheres are transparent but bend and scatter the light that passes through them in predictable ways according to the angle that the light takes when it hits the nanosphere.

The researchers control the nanolithography by altering the size of the nanosphere the duration of light exposures and the angle wavelength and polarization of light.

The researchers can also use one beam of light or multiple beams of light allowing them to create a wide variety of nanostructure designs.

We are using the nanosphere to shape the pattern of light which gives us the ability to shape the resulting nanostructure in three dimensions without using the expensive equipment required by conventional techniques Chang says.

The researchers have shown also that they can get the nanospheres to self-assemble in a regularly-spaced array

We're exploring the use of nanosphere materials other than polystyrene as well as nanoparticle shapes other than spheres Chang says.

Their results have been published in the current online issue of the renowned journal Nature Nanotechnology. A precise control and manipulation of quantum-mechanical states could pave the way for promising applications such as quantum computers and quantum cryptography.

This innovation in nanotechnology won't soak up enough carbon to solve global warming researchers say. However it will provide an environmentally friendly low-cost way to make nanoporous graphene for use in supercapacitors-devices that can store energy and release it rapidly.

Google have been similarly vague about the precise form of nanotechnology they aim to use Graham points out:

How does all this fit into the wider field of nanotechnology and diagnostics? This isn't all about Google says Graham.

it seems according to this article in Wired that Gambhir originally advised Google about nanotechnology. What are the current challenges facing nanodetectors?

In Professor Graham's view there are two serious hurdles for nanotechnologists to overcome before particle-based biosensing becomes a reality:

Are there any other applications of nanotechnology in the field of cancer? Of course it's not all about diagnostics.

There are other ways nanotechnology is being explored by cancer researchers. The other big focus of nanotech in cancer is to deliver treatments says Graham.

This is a field that's in its infancy lots of basic research in animals some of it promising

Professor Graham's'take-home'message is that it's a mistake to see Google as the only organisation focusing on nanotechnology to detect disease it's a vibrant active field with incredible potential but still in its early days.
