Synopsis: Domenii: Nanotechnology: Nanotechnology generale: Nanomaterials: Aggregated diamond nanorod:

Published in Nature Nanotechnology researchers from Cardiff University have unveiled a new method for viewing nanodiamonds inside human living cells for purposes of biomedical research.

Nanodiamonds are very small particles (a thousand times smaller than human hair) and because of their low toxicity they can be used as a carrier to transport drugs inside cells.

There is a growing consensus among scientists that nanodiamonds are one of the best inorganic material alternatives for use in biomedical research, because of their compatibility with human cells,

Previous attempts by other research teams to visualise nanodiamonds under powerful light microscopes have run into the obstacle that the diamond material per se is transparent to visible light.

Locating the nanodiamonds under a microscope had relied on tiny defects in the crystal lattice which fluoresce under light illumination.

and in turn the image gleaned from the microscopic exploration of these flawed nanodiamonds, is sometimes also unstable.

In their latest paper, researchers from Cardiff University's Schools of Biosciences and Physics showed that non-fluorescing nanodiamonds (diamonds without defects) can be imaged optically

By focusing these laser beams onto the nanodiamond, a high-resolution CARS image is generated. Using an in-house built microscope,

the research team was able to measure the intensity of the CARS light on a series of single nanodiamonds of different sizes.

The nanodiamond size was measured accurately by means of electron microscopy and other quantitative optical contrast methods developed within the researcher's lab. In this way,

and number of nanodiamonds that had been delivered into living cells, with a level of accuracy hitherto not achieved by other methods.

The next step for us will be to push the technique to detect nanodiamonds of even smaller sizes than what we have shown so far

#Inner Space of Carbon nanotubes Could act as a Template for Synthesis of Linear-Chain Nanodiamonds The inner space of carbon nanotubes can act as a template for the synthesis of nanodiamond-like carbon chains.

Shinohara and his colleagues were able to synthesize a one-dimensional nanodiamond polymeric structure by a relatively simple annealing technique.

The nanotweezer might be used to create devices containing nanodiamond particles or other nanoscale light-emitting structures that can be used to enhance the production of single photons, workhorses of quantum information processing,

"Professor Reilly's team turned its attention to hyperpolarising nanodiamonds, a process of aligning atoms inside a diamond so they create a signal detectable by an MRI SCANNER."

and nanodiamond materials composed of 1-100 million particles, with an end goal of mapping the electron pathways created by XFEL bursts.

They tried incorporating nanodiamond particles into their simulations to see if the hard material could help stabilize the nanoscrolls

The graphene patches spontaneously rolled around the nanodiamonds, which held the scrolls in place and resulted in sustained superlubricity.

The simulation results fed into a new set of experiments with nanodiamonds that confirmed the same."

"Arrayunfortunately, the addition of nanodiamonds did not address the material's aversion to water. The simulations showed that water suppresses the formation of scrolls by increasing the adhesion of graphene to the surface.

it would leave the graphene and nanodiamonds on one side of a moving part, and diamond-like carbon on the other side.

In new findings the researchers have demonstrated how attaching nanodiamonds containing itrogen-vacancy centersto the new metamaterial further enhances the production of single photons, workhorses of quantum information processing,

cryptography and communications technologies. hese results indicate that the brightness of the nanodiamond-based single-photon emitter could be enhanced substantially by placing such an emitter on the surface of the hyperbolic metamaterial,

Placing a nanodiamond containing an NV center on the surface of hyperbolic metamaterials not only enhances the emission of photons,
