Abstract

Silver aggregates find their technological applications in electricity conducting cements and as catalysts in biomedical sciences. We have developped a method for synthesis of colloidal silver aggregates, based in redox reactions. Aggregate size and structure are strongly influenced by preparation physico-chemical conditions. We have investigated the pH influence over the growth mechanism through dynamic and static light scattering techniques. We introduce here an analysis of the sedimentation rate from which the aggregation regime can also be inferred.
