Microfluidic reactor development for controllable synthesis of ZnO particles. (A) Fabrication procedure of 1.5-loop spiral-shaped microfluidic device. The central image is a photograph of the fabricated microreactor with a U.S. quarter coin for scale. The microfluidic channel was filled with a red dye for visualization. (B) is a scheme showing the design parameters of microreactor. (C) is the photograph showing operation of the microfluidic system with two inlets and one outlet for ZnO synthesis. Objects are not drawn to scale.
