Nanoparticle colloids
are mixtures in which metal nanoparticle's are dispersed in a liquid medium. The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged.

Product and Application
We produce semi-monodispersed metal nanoparticles in a wide range of their size and shape by wet chemical synthesis and femtosecond laser ablation in liquids. probes sensors therapeutic agents conductors catalysts, etc. |
Advantages
Large surface area |
Expressed catalytic properties |
High light absorption in the visible spectrum |
Good biocompatibility after surface functionalization |
Synthesis technology
Technics | Material | Size | Deviation |
---|---|---|---|
Chemical synthesis | Silver | 20 - 200 nm | 4 - 23% |
Physicochemical synthesis (femtosecond laser irradiation of metallic targets situated in pure water) | Gold, silver, copper | 80 - 160 nm | 34 - 36% |
*Depending on the application, nanoparticles can be dispersed in different solvents or deposited on solid or flexible substrates.
Our nanoparticles primarily are prepared as one of the consumables for templated deposition or for your own needs. |
