Many scientists believe that nanotechnology is going to be as pervasive and revolutionary in the 21st century as plastics had been in the last century. By manipulating material properties at atomic level, researchers are expected to develop various promising systems and devices. Ranging from clean manufacturing techniques to amazing advancements in biomedical sciences, nanomaterials are predicted to have a profound impact on human society.

Nanotechnology Basics

Nanotechnology is a generic term used to describe the applications that work with matter so small that it exists in the molecular and atomic realm. As the name indicates, the fundamental unit in any nanotechnology system is a nanometer, nm, which is one billionth part of a meter. Nanotechnology research shows that at such micro level, the physical, chemical and biological properties of materials are different from what they were at large scale.

The fundamental idea is to harness these altered and often improved properties to develop materials, devices and systems that are superior to the existing products. For instance, breaking a material down into nanoparticles allows it to be rebuilt atom by atom, often improving material strength and decreasing weight and dimensions. Based on this concept, researchers have been able to develop a myriad of nanomaterials with amazing properties.
