Abstract

In this article, we present a development of atmospheric pressure plasma jets (APPJs) for modification of liquid solutions. APPJs were fabricated in low temperature cofired ceramics (LTCC) technology. During the measurements, plasma jets worked under various flowing gases, which can be used to produce plasma activated water. In addition, owing to the plasma treatment, it was possible to decrease the time of a synthesis of gold nanoparticles (AuNPs) without the use of additional hazardous reagents. The mechanism of gold nanoparticles formation in cold nitrogen plasma is also presented.

Highlights

Plasma is one of the four fundamental states of matter which is an ionized gas exhibiting collective behavior
Two possible applications of plasma jets were presented in this article: AuNPS production without heavy species and production of the plasma activated water (PAW)
Optical methods were used to describe the species present in plasma and the results obtained in nanoparticles synthesis

Summary

Introduction

Plasma is one of the four fundamental states of matter which is an ionized gas exhibiting collective behavior It can be generated by delivering sufficient amount of energy in a specific form, e.g., in electrical DC and AC discharges. Cold plasma jets are the most interesting among other plasma devices They have numerous advantages such as generation of plasma under atmospheric pressure, simple construction and a variety of properties of the generated plasma [1]. They can be used for the treatment of solids or liquids surfaces, their modification, biologic sterilization or chemical synthesis [2]. Typical plasma jets are made by means of fine mechanics They have some drawbacks, such as high power consumption and generation of thermal (hot) plasmas. Hot plasmas reach temperatures of more than 10,000 K, which is required in spraying of high melting point metals and alloys, but it excludes them from other applications
