I thought colloidal meant 'smallest particle'. dee On 17 Dec 2009, at 16:33, frankcuns-r...@comcast.net wrote: Rusty, Nano refers to a certain size. Separate atoms or ions of silver are well in the nano range. Colloidal means a state of association or bunching of atoms or ions where these clusters are suspended in a fluid (water) If the clusters are large enough they will sink to the bottom of the container. If they are small enough they "float" and take a long time to settle. The popular wisdom is that small colloidal clusters are more effective.
