Gold nanoparticle (AuNP) formation by applying pulsed discharge plasma in the slug flow reactor system was demonstrated. Experiments were carried out continuously at room temperature. The argon gas as a gas phase and the hydrogen tetrachloroaurate(III) tetra hydrate solution containing lysine as a liquid phase simultaneously flowed in the slug flow reactor system. The flow rates of the feed solution and argon gas were kept at 1.5 and 0.2 mL/min, respectively. To generate discharge plasma, the AC power supply with a bipolar pulsed output at 10 kV was applied. The purple color solution product was obtained, and the ultraviolet–visible (UV–vis) spectrophotometer showed that this possessed the absorption light from 510 to 550 nm associated with the existence of gold nanoparticles in each collected sample. Transmission electron microscopy (TEM) revealed that the lysine-capped AuNPs were produced in a spherical morphology and dispersed in aqueous solution products with a diameter of less than 20 nm.

弹流反应器系统中的大气压脉冲放电等离子体用于合成金纳米粒子。
演示了通过在段塞流反应器系统中应用脉冲放电等离子体来形成金纳米粒子（AuNP）。实验在室温下连续进行。作为气相的氩气和作为液相的含有赖氨酸的四氯金酸(III)四水合物溶液同时流入段塞流反应器系统中。进料溶液和氩气的流速分别保持在1.5和0.2mL/min。为了产生放电等离子体，使用具有 10 kV 双极脉冲输出的交流电源。获得紫色溶液产物，紫外可见分光光度计显示其具有 510 至 550 nm 的吸收光，这与每个收集的样品中金纳米颗粒的存在有关。透射电子显微镜（TEM）显示赖氨酸封端的AuNPs呈球形形态并分散在直径小于20 nm的水溶液产物中。
