Colloids

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.

Nanoparticles are applied in different fields from biomedicine to electronics and can be used as:

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.
