Silver Nanoparticles
Colloidal and powder grades
Silver nanoparticles (AgNPs) combine a high surface-area-to-volume ratio with strong surface reactivity and distinctive optical properties. We supply a colloidal grade for liquid formulations and a high-purity powder for materials and research.

Technical overview
Silver nanoparticles are typically 1–100 nm in size. Colloidal solutions may appear yellow, light brown or dark brown depending on particle size, concentration and formulation.
Stabilisers such as polyvinylpyrrolidone (PVP) and citrate help prevent aggregation and improve colloidal stability.
