Silver nanoparticles – These are the nanoparticles of silver which is described being as silver having a large percentage of silver oxide due to their large ratio of surface-to-bulk silver atoms. Well, the particles have found to use for the applications in catalysis, optics, electronics, and other areas due to their unique size-dependent optical, electrical, and magnetic properties.

Gold Nanoparticle – These are the suspension of sub-micrometre-sized particles of gold having either an intense red color or a dirty yellowish color. These nanoparticle are certainly used for substantial research in variety of areas, including electron microscopy, electronics and nanotechnology materials science etc.

Aluminum Nanoparticle – These are the nanoparticles of Aluminum, which reacts with water molecules to split oxygen and hydrogen bonds. It is used for the purpose of Geo-engineering etc.

Well, as you can see from the above the nanoparticles have certainly used for varies researches. Hence, if you are one of those found to be in some research kind of stuffs to then you can log on to ssnano.com to purchase these. For your brief knowledge - ssnano.com is selling wide range of rare earth materials as well as nanoparticles such as silver nanoparticles, gold nanoparticles, and aluminum nanoparticle etc. You can buy these from its official website of ssnano.com certainly.
