Abstract: In order to controllably prepare gold nanoparticles with uniform size and good morphology, a synthesis method based on Surface Acoustic Wave (SAW) is proposed. The controllable microfluidic system based on SAW is used to perturb the synthesizing process and realize the controlled synthesis of gold nanoparticles. The parameters of the Interdigital Transducers (IDTs) are designed and the number of IDTs is optimized by MATLAB. Afterward, the controllable microfluidic system based on SAW is designed and manufactured. The experiments under different voltages are carried out to analyze the influence of voltage on the experiment results. Results show that the gold nanoparticles with different concentrations, morphologies and monodisperses can be synthesized under different loading voltages, which further verifies the controllability and feasibility of the proposed synthesis method.

Key words: fluid transmission and control, surface acouctic wave, piezoelectric actuation, microfluidic reactor, gold nanoparticles, controlled synthesis
