Introduction

Nanotechnology, derived from the Greek word "nano" meaning dwarf, refers to the manipulation and control of materials at the nanoscale. The nanoscale is the realm of particles that are smaller than what the human eye can see, but larger than individual atoms. The field of nanotechnology has gained significant attention in recent years due to its potential to revolutionize various industries.

Definition and Brief History

Nanotechnology involves the manipulation and control of materials at the nanoscale, which is about 1 to 100 nanometers in size. At this scale, materials exhibit unique properties and behaviors that are different from their bulk counterparts. Nanotechnology encompasses various disciplines, including physics, chemistry, biology, materials science, and engineering, and is considered as a multidisciplinary field.

The concept of nanotechnology was first proposed by physicist Richard Feynman in his famous 1959 lecture "There's Plenty of Room at the Bottom." However, the field gained traction in the 1980s when scientists and researchers started exploring the potential of working at the nanoscale. Since then, nanotechnology has rapidly advanced, and it has found applications in various fields.
