- Abstract
Objective: In order to synthesize the gold nanoparticles with high sphericility, good monodispersity and uniform sizes, a method of synthesizing by integrated modular microfluidic reactor based on piezoelectric actuation is proposed. Method: First, the entrance angle and channel section of the micromixing channel of microreactor are simulated by the software FLUENT, and the related structure parameters are optimized. Second, the two modules of microreactor chips including micromixing chip and growing channel chip are designed, and the microreactor prototype is fabricated. Finally, the synthesis tests of gold nanoparticles based on liquidus chemical reaction are carried out, and the characteristics of the obtained specimen are tested by UV-VIS spectrophotometer and transmission electron microscopy. Result: The test result indicates that with the output flow rate of 4.2ml/min and the frequency of 200 Hz, the average particle size and standard deviation of the obtained gold nanoparticles is (27.89ñ5.28) nm, and the nanoparticles have uniform sizes, good monodispersity, and high sphericility. Conclusion: The result verifies the feasibility of using the microfluidic reactor presented in this paper to synthesize gold nanoparticles with uniform sizes and good monodispersity.
