High Purity, D50 = +10 nanometer (nm) by SEMSilver (Ag) Nanoparticles, nanodots or nanopowder are spherical or nanoflake high surface area metal particles with properties and uses that include inhibiting transmission of HIV and other viruses. See Material Safety Data Sheet (MSDS) and recent research.  Nanoscale Silver Particles are available in the size range of 10-200 nm, with specific surface area (SSA) in the 30-60 m 2 /g range and also available as flakes with an average particle size of  2-10 micron range with a specific surface area of approximately 40-80 m 2 /g. Nano Silver Particles are also available in Ultra high purity and high purity, coated, oleic oil-coated, dispersed, and polymer-dispersed forms. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers.

Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil.. Applications for silver nanocrystals and flakes include as an anti-microbial, anti-bacterial, anti-viral, anti-biotic and anti-fungal agent when incorporated in coatings, nanofiber, first aid bandages, dressings, sticking plasters, plastics, soap and textiles, in self cleaning fabrics, and as conductive filler. It is also used in nanowire and in certain catalyst applications. S-MITE HIV Inhibator is a proprietary form of silver nano powder that has been shown to deactivate HIV by inhibiting the virus from attaching to the host with undetectable levels of cytotoxicity. HIV medical health creams may prevent sexual transmission of HIV-1. See the Silver Nanoparticles Product  Data Sheet. Silver Nano Particles are generally immediately available in most volumes. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Silver (Ag)atomic and molecular weight, atomic number and elemental symbolSilver (atomic symbol: Ag, atomic number: 47) is a Block D, Group 11, Period 5 element with an atomic weight of 107.8682. Silver Bohr ModelThe number of electrons in each of Silver's shells is 2, 8, 18, 18, 1 and its electron configuration is [Kr]4d10 5s1. The silver atom has a radius of 144 pm and a Van der Waals radius of 203 pm. Silver was first discovered by Early Man prior to 5000 BC. In its elemental form, silver has a brilliant white metallic luster. Elemental SilverIt is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. It is found in copper, copper-nickel, lead, and lead-zinc ores among others. Silver was named after the Anglo-Saxon word "seolfor" or "siolfur," meaning 'silver'.
