Plasma is the fourth state of matter after solid, liquid, and gas states. However, this definition may be slightly confusing. More precisely, the plasma can be defined as a gas which is fully or partially ionized. According to this definition, plasma is a gaseous medium consisting of molecules, atoms, ions, and electrons. Due to the presence of charged particles, plasma has an electrical conductivity and is also strongly influenced by electric and magnetic fields.

Plasma is an ionized gas in which whole or a significant portion of its atoms have lost one or several electrons, and turned into positive ions. In recent decades, plasma technology has been used for some applications such as surface modification and cleaning. Plasma cleaning is a process in which all organic compounds are removed from the surface by using plasma.
