Metal Nano Powder

Gold Nanopowder Use wavelength modulation approach, i.e., the spectroscopy of a surface plasmon in the frequency domain, to characterize the optical dispersion property of gold film. Using this method, the dispersion relationship of gold film in a wavelength range from 537.12 nm to 905.52 nm, The optical dispersion properties of thin metal films, because a series of dielectric constants over a wide spectral range can be determined simultaneously via only a single scan of the incident angle, thereby avoiding the repeated measurements required when using the angular modulation approach.

Gold Nanopowder has various applications in the Pharmaceutical and Medical field. Drug delivery has impacted by the advancement in nano powders smaller particles are able to be delivered in new ways to patients, through solutions, oral or injected, and aerosol, inhaler or respirator. New production processes allow for encapsulation of pharmaceuticals which allow for drug delivery where needed with in the body. From nanotechnology we can be able to understand the living cells and used in studies like, enhanced spectroscopic techniques, biochips, and protein and enzyme analysis.

Gold Nanopowder is prepared by dispersing 20nm or even smaller gold nanoparticles into water solution. The preparation will end up with uniform neutral solution with stable color. The gold nanoparticles solution appears to be faint red not golden brown. he cosmetic product,Au nanoparticles play a role of whitening, anti-aging and emollients; or as Food colorants organisms; Genetic identification; Environmental purification products for refining; Used in food, cosmetics as preservatives; Applied to the production of antibacterial, antimicrobial, anti-inflammatory drugs, and medical equipment, health supplies, beauty care equipment. Living daily commodity, such as food, beverages, nano-gold soap, toothbrushes, all kinds of beauty mask etc.

Gold Nanopowder increase the size range of metal nanoparticles which can be dispersed in nonpolar solvents, attractive interparticle forces must be countered by greater short-range repulsion by designing surfactant layers with high conformational entropy. Many polymeric surfactants are excellent dispersants because of their elasticities; however, such coatings on nanoparticles are often nonuniform or are poorly suited for applications requiring monolayer thickness.

Gold Nanopowder The color of colloidal dispersions of gold particles in a fluid, typically water, varies from red to blue, depending upon the shape and size of particles. The color and optical properties of gold nanoparticles originate from localized surface plasmons, and are sensitive to their local dielectric environment. Unlike nanospheres, the optical properties, hydrodynamic behavior as well as phase behavior of nanorods are influenced by their shape anisotropy.
