Nanotechnology involves manipulating matter at the atomic and molecular scale between 1 to 100 nanometers. It deals with developing materials, devices, and structures at the nanoscale. Some challenges include fully understanding how atoms and molecules behave and interact at such small scales, and how quantum mechanics impacts substances at the nanoscale. There are also concerns that some nanoparticles could be toxic if inhaled or absorbed through the skin due to their small size enabling access to tissues and organs. Potential applications of nanotechnology include nano robots, aerospace technologies, automobiles, medical devices, and coatings for products like sunscreen and self-cleaning glass.

This document provides an overview of nanotechnology. It defines nanotechnology as the study and engineering of matter at the nanoscale, or atomic level. The document outlines the history of nanotechnology from its conception in 1959 to modern applications. Key tools used in nanotechnology like atomic force microscopes and carbon nanotubes are described. The document also discusses different approaches (top-down vs bottom-up), materials used, and applications of nanotechnology in areas like drugs, fabrics, electronics, and computers. It provides examples of how nanotechnology is enhancing performance in these domains.
