Unconjugated silver colloids

Nanometre sized silver particles of uniform shape and size are invaluable tools in nanotechnology, eg. assembled arrays, light scattering etc.

The colloids can be conjugated to antibodies, proteins or many types of macromolecules for binding and reaction labelling studies. The colloids are manufactured with a very narrow size distribution.

The silver colloids are available in size range 20 - 80nm. These are not as well characterised as the gold but give alternative optical properties.

Please note: These products require refrigeration storage between 2-8˚C. As a result, and to retain the integrity of the product, we will not ship on Fridays or where we cannot confirm a next day delivery.
