2. History and evolution of nanotechnology

A Blast from the Past: How Nanotechnology Evolved from Ancient Alchemy to Modern Marvel?

Nanotechnology may sound like a future notion, but its origins are astonishingly deep. While purposeful manipulation of materials at the atomic level is a relatively new discovery, the foundation for nanotechnology was built much earlier than you might expect.

Ancient Seeds of Modern Science

Believe it or not, our forefathers were unknowingly employing nanotechnology for millennia! Craftspeople from civilizations as ancient as the Romans and Islamic dynasties employed nanoscale materials without understanding it. The bright hues of Lycurgus Cups, a form of Roman glassware, are due to the presence of gold and silver nanoparticles that interact with light.

The Origin of a Visionary Idea

Fast forward to the 1950s, and enter the brilliant physicist Richard Feynman. Feynman, known as the "father of nanotechnology," pioneered the concept of altering matter at the atomic and molecular level in his 1959 address "There's Plenty of Room at the Bottom" (mottotahraf kard). He challenged scientists to investigate the feasibility of creating machines so small that they could work on individual atoms.

The Tools Make A Difference

Nanotechnology experienced a watershed moment in the 1980s. The scanning tunneling microscope (STM), invented in 1981, was a game changer. This new instrument enabled scientists to observe individual atoms and manipulate them with remarkable precision. This began a new era of nanoscale experimentation and discovery.

The beginning of the nanomaterial boom.

The discovery of fullerenes in 1985 fuelled the nanotechnology fire. These distinct carbon molecules with spherical or cage-like shapes demonstrated extraordinary characteristics and prompted intense scientific curiosity. Carbon nanotubes, another remarkable family of nanomaterials with exceptional strength and conductivity, were the focus of much research in the 1990s.
