What is Gold Colloidal Nano Dispersion?
Gold colloidal nano dispersion refers to a stable suspension of ultra-fine gold nanoparticles dispersed uniformly in water or aqueous media. These nanoparticles typically range between 20–50 nm, offering unique optical, electrical, thermal, and chemical properties that differ significantly from bulk gold.
At the nanoscale, gold exhibits:
- Enhanced surface reactivity
- High electrical conductivity
- Strong optical absorption and scattering
- Catalytic behavior
- Biocompatibility
NanowizTech ensures that each batch of gold nano dispersion maintains high monodispersity, excellent stability, and controlled particle size distribution for reproducible performance.
