Recently, numerous research and development projects have been reported on microchemical analytical systems (μ-TAS) and lab-on-chips that utilize microfluidic technology. These microreactors are devices that induce chemical reactions in a microscopic space. Because of their extremely large reaction surface area per unit volume, specific and efficient reactions at liquid-liquid and gas-liquid phase interfaces have been reported. Therefore, combining microfluidic technology with atmospheric pressure plasma is expected to improve the efficiency and precision of previously reported gas-liquid interfacial plasma chemical reactions. Previously, we fabricated a prototype minichannel plate in which a T-shaped junction was installed in a 1 mm hydraulic minichannel to form a gas-liquid two-phase flow of He gas and liquid, and then pulsed discharge was used to generate gas-liquid interfacial plasma within the channel. In this study, we report on the synthesis of gold nanoparticles (AuNPs) by plasma reduction using a prototype minichannel plate.
