Nano colloidal gold for sale

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

Nano gold colloids(hwnanomaterial) have good stability, small size effect, surface effect, optical effect and unique biocompatibility. It has been widely used in industrial catalysis, biomedicine, bioanalytical chemistry, rapid detection of food arrangement and other fields.

our aluminum nanopowder available in 100nm, 200nm both with 99.9% purity could apply to the firework, as the catalyst so on.

Nano bi2o3 powder, yellow powder, widely used as electronic component materials.

      Titanium dioxide material can selectively etch metal nanoparticles through electron transfer with metal Ag nanoparticles in the excited state, and change the optical absorption characteristics of the material, thus the Ag/Tio2 nanomaterials can change color under the light excitation of different wavelengths.       Experimental demonstration: 1) 500 ℃ heat treatment was carried out on the TIO2 thin film，it is helpful for photocatalytic deposition of Ag particles, and Ag/TIO2 thin film has the obvious photochromic phenomenon; 2) as the content increase of Ag particles deposited on TIO2 films, the photochromic rate of Ag/TIO2 films increases correspondingly, but the reaction rate of photochromic reaction is inhibited when the content of Ag particles exceeds a certain amount.       If you're interested in the material, please not hesitate to contact us , and we will make a tailor for matching your products.
