A synthesis of gold nanoparticles dispersion in toluene by mixing immiscible solutions in a microchannel was proposed. The visualization test using red and blue ink aqueous solutions as a substitute for gold ion and reducing agent confirmed that the fluid showed the slug flow at below the flow rate of 0.3mL/min. The synthesis results found that gold nanoparticles with diameter from 3.0 to 4.1nm was prepared at slug flow in the microchannel, and size control of gold nanoparticle enable by changing the flow rate.
