Abstract
Methods for preparing highly stable concentrated dispersions of silver nanoparticles and described herein. Contemplated methods comprise combining a selected polysaccharidic dispersant with a selected non-reacting dispersant to yield concentrated silver dispersions with enhanced stability and lowered undesirable residual organics. Contemplated methods further comprise selecting an appropriate source of silver ions to reduce the ionic strength of the reaction medium and final silver dispersions.
