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
