Start-up Particular uses lasers to produce better nanotechnology products

(July 1, 2010) — A new German nanotechnology company has started its business: Particular GmbH has commercialized a novel process for the production of highly pure nanoparticles.

The developments were made at Laser Zentrum Hannover e. V. (LZH) and took five years. Niko Bärsch, CEO of Particular, explains that their nanoparticles make it easier to take advantage of nanotechnology for many products, especially in the field of medical technology.

Nanoparticles are invisibly small material pieces that improve products’ biological compatibility, bacteria resistance, UV light absorption, or scratch resistance. While they are usually generated chemically, the new company produces them physically by laser ablation in liquids. This enables new kinds of nanoparticles, for example for metallic surfaces with securely attached nanostructures that make implants more compatible, or for a conjugation of smallest gold particles and biomolecules for biomedical applications such as cell separations.
