N2 - We have developed a novel centrifugal microdevice for stepwise chemical reagent loading to synthesize highthroughput gold nanoparticles. The proposed disc-shaped microdevice contains 30 functional units, each of which consists of a reaction chamber and three reservoirs for a control solution, a seed solution, and a growth solution. The reservoirs were connected to the main channel via different dimensional microfluidic channels, and the main channel was linked to the reaction chamber. Through control of rotational speed, we could load the growth, seed, and control solution sequentially to the reaction chamber, and proceed the gold nanoparticle synthesis in a high-throughput manner. By tuning the concentration of ascorbic acid as a control solution, various shape of gold nanoparticles was generated simultaneously.
