摘要： Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

摘要： A gold powder comprising gold having a purity of 99.9% by mass or more and having an average particle size of 0.01 μm or more and 1.0 μm or less, a content of a chloride ion is 100 ppm or less, and a content of a cyanide ion is 10 ppm or more and 1000 ppm or less. A total of the content of a chloride ion and the content of a cyanide ion is preferably 110 ppm or more and 1000 ppm or less. The gold powder has improved adaptability to various processes including bonding or the like with a content of a chloride ion, that is, an impurity, optimized.

摘要： Producing CoxFe100-x, where x is an integer from 20 to 95, nanoparticles by: (a) providing a first aqueous hydroxide solution; (b) preparing a second aqueous solution containing iron ions and cobalt ions; and (c) depositing measured volumes of the second aqueous solution into the first aqueous solution whereby coprecipitation yields CoFe alloy nanoparticles, wherein step (c) occurs in an essentially oxygen-free environment. The nanoparticles are annealed at ambient temperatures to yield soft nanoparticles with targeted particle size, saturation magnetization and coercivity. The chemical composition, crystal structure and homogeneity are controlled at the atomic level. The CoFe magnetic nanoparticles have Ms of 200-235 emu/g, (Hc) coercivity of 18 to 36 Oe and size range of 5-40 nm. The high magnetic moment CoFe nanoparticles can be employed in drug delivery, superior contrast agents for highly sensitive magnetic resonance imaging, magnetic immunoassay, magnetic labeling, waste water treatment, and magnetic separation.
