1-INTRODUCTION

Nanotechnology is transforming numerous areas such as science, medicine, engineering, energy, plastics, and aerospace by manipulating materials at the atomic and molecular levels. With nanotechnology, it becomes feasible to fabricate materials from fundamental units, at the atomic scale, which possess improved electronic, magnetic, optical, and chemical characteristics.

• Technologies that operate, function, or apply at the “nanometer” level are grouped together under the term “Nanotechnology”.
• The term “Nano” derives from the Greek word “Nanos” meaning, “dwarf”.
• Nano materials refer to the substances that have sizes ranging from one to 100 nanometers (nm).
• 1nm=10^-9
