Abstract: Microplasma is now becoming an important field of research on non-thermal plasma. Spatial confinement to dimensions of 1mm or less and operation at atmospheric pressure gives microplasma many advantages like low power consumption, high density, high stability and convenient portability. All these advantages open the door to a wide range of new applications of microplasma in areas such as ultraviolet sources, analytical chemistry, biomedicine, surface treatment and environmental remediation. This paper reviews a variety of methods generating microplasma and its applications in different fields.
