Nearly all the aspects of dusty plasmas like Dynamics of Dusty Plasmas, Debye length, Applications of Dusty Plasmas in Industry and Astrophysics, Plasma Treatment for Biomedical Field, Applications of Dusty Plasmas in Material Science, and Devices for Plasma Diagnostics, have been discussed in this book in quite detail. For giving a deeper understanding of the Debye length, its significance in electrolytic solution and semiconductor, in addition to that in dusty plasma has also been given. In order to broaden the area of the applications of plasma science, a Chapter on the Plasma Treatment for Biomedical Applications, has also been added, since the applications of dusty plasmas are in general limited to Industry and Astrophysics; and Material Science. However, this chapter also touches a brief discussion of the use of dusty plasmas in Biology and Medicine.
