Electron ping pong in the nano-world

(PhysOrg.com) -- An international team of researchers succeeded at the Max Planck Institute of Quantum Optics to control and monitor strongly accelerated electrons from nano-spheres with extremely short and intense laser ...

Researchers use 3-D printing to make glass optical fiber preform

Researchers have developed a way to use 3-D printing to create a preform that can be drawn into silica glass optical fibers, which form the backbone of the global telecommunications network. This new fabrication method could ...

Nanoparticles on track to distinguish tumour tissue

Gold nanoparticles could be used to help detect the margins between tumours and normal tissue, enabling surgeons to better determine which tissue to remove and which to leave.

Coating noble metal nanoparticles with silica

A straightforward and effective process for coating silver, gold and platinum nanoparticles with functionalized silica shells at room temperature has been developed by A*STAR . Crucially, unlike conventional methods for producing ...

A Good Eye for Oxygen

(PhysOrg.com) -- We cannot live without it; yet too much of it causes damage: oxygen is a critical component of many physiological and pathological processes in living cells. Oxygen deficiency in tissues is thus related to ...

Nanoparticle toxicity doesn't get wacky at the smallest sizes

(PhysOrg.com) -- The smallest nano-sized silica particles used in biomedicine and engineering likely won't cause unexpected biological responses due to their size, according to work presented today. The result should allay ...
