Concentrated dispersions of uniform silver nanoparticles and methods for preparing the same

Abstract

Provided herein are compositions comprising concentrated dispersions of silver nanoparticles. Also provided herein are methods of preparing concentrated dispersions of silver nanoparticles. Such a method includes preparing a dextran solution comprising silver or silver ions, preparing a silver precursor solution, and mixing the silver precursor solution with the dextran solution under conditions for a rapid reaction wherein the pH is above about 9 and the temperature above about 40 degrees Celsius, thereby forming the concentrated dispersion of silver nanoparticles.
