Life Technologies files patent US20120228565: Method for preparing surface-modified semiconductive and metallic nanoparticles having enhanced dispersibility in aqueous media

Water-dispersible nanoparticles are prepared by applying a coating of a multiply amphipathic dispersant to the surface of a hydrophobic nanoparticle comprised of a semiconductive or metallic material. The multiply amphipathic dispersant has two or more hydrophobic regions and two or more hydrophilic regions, and is typically polymeric. Preferred polymeric dispersants are comprised of (1) a…
