INTRODUCTION

The National Nanotechnology Initiative (NNI), established in 2001 to coordinate Federal nanotechnology research and development, defines nanotechnology as i) research and technology development at the atomic, molecular, or macromolecular levels in the length scale of approximately the 1- to 100-nanometer range; ii) creating and using structures, devices, and systems that have novel properties and functions because of their small and/or intermediate size; and iii) the ability to control or manipulate on the atomic scale (1). Generally speaking, nanotechnology can be defined as the application of scientific and engineering principles to make and utilize very small things. Nanotechnology is moving into the centre of world-wide public attention because of its broad range of applications which could dramatically impact both the scientific community and the commercial marketplace. Nanotechnology applications have been applied across biomedical, optical, electronic, mechanical, an
