Nanotechnology And Economic Impact

Key Concepts and Definitions

Nanotechnology refers to the manipulation of matter at the nanoscale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique properties such as increased strength, lighter weight, enhanced chemical reactivity, and improved electrical conductivity. These properties enable innovations across various sectors, driving economic growth and creating new opportunities.

Economic impact, in the context of nanotechnology, encompasses the ways in which this field influences industries, job creation, market dynamics, and global trade. It includes direct contributions, such as the development of nanomaterials and nanodevices, and indirect effects, such as the transformation of existing industries and the creation of entirely new markets.

Historical Milestones in Nanotechnology

Nanotechnology's journey began with Richard Feynman's famous lecture, "There's Plenty of Room at the Bottom," in 1959, where he envisioned manipulating atoms to create new materials. The field gained momentum in the 1980s with the invention of the scanning tunneling microscope (STM), which allowed scientists to visualize and manipulate individual atoms.

Key milestones include:

• 1981: Development of the STM by Gerd Binnig and Heinrich Rohrer, earning them the Nobel Prize in Physics.
• 1991: Discovery of carbon nanotubes by Sumio Iijima, revolutionizing material science.
