Nanotechnology opens new frontiers in science, engineering

Mihail C. Roco

Nanotechnology has ushered in a revolutionary age of promise and possibilities that within a few decades will touch nearly every aspect of our lives.

In the next 30 years, we may experience more technological advances — from nanoscale manufacturing, medicine, education and leisure — than the amazing advances realized throughout the entire 20th century.

Research at the nano level will teach us how to build new materials and tiny structures by assembling atoms or molecules with high precision instead of the more conventional approach of sculpting parts from pre-existing materials.

Nanotechnology promises to increase efficiency in traditional industries and bring radically new applications through emerging technologies. For example, we will improve our ability to detect and treat cancer in its earlier stages, reducing suffering and saving lives.

This technology is producing a new class of ultra-small, ultra-powerful computers and electronic devices. It also helps in building lighter and stronger materials for cars, buses and other transportation vehicles.

In light of these advances, support for nanotechnology research and development has burgeoned. In the last seven years,
