Nanotechnologists collaborate to form near-frictionless diamond material (3/1/2010)

Mechanical engineers have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon. The end result is a diamond-like carbon material mass-produced at the nanoscale that doesn't wear. ...> Full Article

For nanowires, nothing sparkles quite like diamond (2/19/2010)

Diamonds are renowned for their seemingly flawless physical beauty and their interplay with light. Now researchers are taking advantage of the mineral's imperfections to control that light at the atomic scale, generating one photon at a time. ...> Full Article

Digging deep into diamonds, applied physicists advance quantum science and technology (2/15/2010)

By creating diamond-based nanowire devices, a team at Harvard has taken another step towards making applications based on quantum science and technology possible. The new device offers a bright, stable source of single photons at room temperature, an essential element in making fast and secure computing with light practical. ...> Full Article

Game-changing nanodiamond discovery for MRI (1/15/2010)

A Northwestern University study shows that coupling a magnetic resonance imaging contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast. The researchers say it is a game-changing event for sensitivity and the first published report of nanodiamonds being imaged by MRI technology. The gadolinium(III)-nanodiamond complex demonstrated a greater than 10-fold increase in relaxivity -- among the highest per Gd(III) values reported to date. ...> Full Article

New nanocrystalline diamond probes overcome wear (11/12/2009)

Researchers at the McCormick School of Engineering and Applied Science at Northwestern University have developed, characterized, and modeled a new kind of probe used in atomic force microscopy, which images, measures, and manipulates matter at the nanoscale. Using diamond, researchers made a much more durable probe than the commercially available silicon nitride probes, which are typically used in AFM to gather information from a material, but can wear down after several uses. ...> Full Article

Nanodiamonds deliver insulin for wound healing (7/28/2009)

Using tiny nanodiamonds, researchers at Northwestern University have demonstrated an innovative method for delivering and releasing insulin at a specific location over a period of time. The nanodiamond-insulin clusters hold promise for wound-healing applications and could be integrated into gels, ointments, bandages or suture materials. ...> Full Article

A breakthrough toward industrial production of fluorescent nanodiamonds (6/5/2009)

The laboratory Structure -- Activity of Normal and Pathologic Biomolecules-Inserm, in collaboration with the Material Center of Mines-ParisTech, the NRG-UMR 5060 CNRS/UTBM and the Physic Institute of Stuttgart University, discovered a novel route to fabricate fluorescent nanoparticles from diamond microcrystals. Results are published in Nanotechnology's June 10 issue. ...> Full Article
