COMPREHENSIVE STUDY& OVERVIEW OF NANOTECHNOLOGY

Abstract

Nanotechnology is the engineering of functional systems at the molecular scale. This covers both
current work and concepts that are more advanced. In its original sense, ‘nanotechnology’ refers
to the projected ability to construct items from the bottom-up, using techniques and tools being
developed today to make complete, high performance products. The main unifying theme is the
control of matter on a scale smaller than one micrometer, normally approximately 1 to 100
nanometers, as well as the fabrication of devices of these sizes. It is a highly multidisciplinary
field, drawing from fields such as applied physics, superamolecular chemistry and even
electrical and mechanical engineering. Nanotechnology can be seen as extension of existing
sciences using newer and more modern term.
