AbstractLab-on-a-chip (LOC) systems are extensively used in recent times for applications in nanotechnology ranging from synthesis of nanomaterials to their utilization in catalysis, biomedicine, and drug delivery. A variety of nanomaterials – inorganic materials such as metal, metal oxide, quantum dots, and organic materials based on polymers and biological molecules – have been synthesized and their applications explored based on LOC devices. Among several inorganic nanomaterials, the applications of LOC devices for gold-based nanomaterials have been widely investigated over the past couple of decades. Though the synthesis and applications of inorganic nanomaterials using these systems have been thoroughly reviewed earlier, including those from our group, there are only a few recent review articles that cover gold-based nanomaterials. As the promise of supported gold nanoparticles (NPs) as exceptionally effective catalysts is beginning to be realized, LOC-based approach for continuous flow gold catalysis has begun to be exploited. Here, in this review, we focus on synthesis and catalysis applications of nanostructured gold using the LOC systems. With millifluidics-based LOCs gaining traction, this review fulfills the need for a comprehensive analysis covering both traditional microfluidics as well as recent millifluidics for catalysis applications utilizing gold nanomaterials.

Abstract Plasma contacting with liquid provides many charged particles and reactive species into the liquid. The difficulty in controlling or selecting each specific species has significantly limited its applications in industry. Here, we present a study on using voltage polarity to regulate the type of charged particles absorbing from plasma into liquid. Detailed understanding of the processes at the plasma-liquid interface, electrolysis due to switching in voltage polarity was investigated via a visual pH observation, measuring the concentration of H2O2 and solvated electrons. The results indicated that changing in voltage polarity strongly affects the plasma properties, chemical properties, and electrolysis process in liquid, and further in the types of reducing species for gold nanoparticle synthesis. The results also showed using a suitable frequency could improve the efficiency of absorption of H2O2from plasma into the bulk liquid and the yield in the production of gold nanoparticles. The results provide a way to select desired species from plasma into the liquid for a distinct purpose and accompanying other properties in the system of plasma contacting with liquid.
