Strem Chemicals, Inc., a manufacturer of specialty chemicals for research and development, is pleased to announce the addition of Reactant & Surfactant-Free Pure Nanoparticles to its portfolio of nanomaterials.
Strem Chemicals adds Pure Nanoparticles generated by laser ablation
The laser ablation technology used by manufacturer Particular GmbH of Hannover, Germany involves the physical production of nanoparticles from a pure metal target in pure water or solvent, providing nanoparticles free of any contaminants, such as unreacted starting materials.
In addition, nanoparticles produced via laser ablation have a positive charge on the surface. As a result, electrostatic stabilization by the surrounding medium occurs without the need, in most cases, for any type of chemical stabilizer (a small amount of citrate is used in aqueous solutions). The nanoparticles can also be readily functionalized and/or permanently immobilized on micro- and nanoparticulate supports.
Furthermore, a wide range of carriers, including volatile organic solvents and reactive monomers, and almost any solid or powder material can be converted into a colloid using laser ablation. The current product range includes aqueous and solvent-based dispersions of silver, gold, platinum, palladium rhodium, ruthenium, copper, and titanium nanoparticles.
"The higher reactivity and lower toxicity of Particular's nanoparticles make them very attractive for medical diagnostic and catalytic applications. We are excited to expand our portfolio of advanced nanomaterial technologies and provide our customers with access to these unique, high purity nanoparticle dispersions," said Chief Operating Officer Dr. Ephraim Honig.
Particular's Laser Ablation-generated nanoparticles are sold in collaboration with Particular for research purposes. They have potential applications in biomedical, immunoassay, and toxicology studies; environmental analysis; targeted drug delivery applications; as supported heterogeneous catalysts; and in nanocoatings and nanocomposites.
"Strem's customers will surely achieve good results in their nanotech developments when they apply our pure metal colloids" said Dr. Niko Baersch, CEO at Particular. "Strem Chemicals is a perfect partner whose customers appreciate their expertise and reliability. We are happy to contribute high-quality materials that customers can use to improve established nano-products or even to realize new nano-innovations."
Strem Chemicals, Inc., established in 1964, is a privately held manufacturer and marketer of specialty chemicals of high purity. Strem's key products include catalysts, ligands, organometallics, metal carbonyls, and nanomaterials. Its products are used for research and development and commercial scale applications, especially in the pharmaceutical, microelectronics, chemicals, and petrochemicals industries.
Particular GmbH from Hannover, Germany, started their business as a nanomaterial supplier in July 2010. The start-up is the first company to employ laser ablation in liquids for a physical production of highly pure nanoparticles, for example from all kinds of metals.
