Abstract: An improved process for synthesising discrete high definition silver nanoparticles in large batch volumes. The method enables the reproducible production of silver nanoparticles having a predetermined size, shape and surface chemistry. The process comprises the steps of forming silver seeds from a reagent comprising, a silver source and a reducing agent; and growing the thus formed silver seeds into silver nanoparticles wherein the step forming silver seeds and/or growing the silver seeds into silver nanoparticles is performed using micro fluidic flow chemistry.
