Introduction to Nanotechnology

Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale, typically smaller than 100 nanometers. It involves creating materials, devices, and systems that have novel properties and functions due to their small size. The unique properties of nanoscale materials, such as increased strength, chemical reactivity, or conductivity, make them ideal candidates for the development of smart materials.

Smart Materials: Definition and Characteristics

Smart materials are designed to respond to external stimuli such as heat, light, stress, or electrical and magnetic fields. They can change their properties or behavior in a controlled manner, enabling them to perform functions that conventional materials cannot.
