Key Figures/Institution

Significance

4th Century

Lycurgus Cup

Roman artisans

Unintentional creation of dichroic glass using gold and silver nanoparticles, demonstrating size-dependent optical effects [1].

1857

Colloidal Gold Experiments

Michael Faraday

First scientific recognition that the optical properties (e.g., color) of a material can change at the nanoscale [2].

1931

Invention of Transmission Electron Microscope (TEM)

Ernst Ruska and Max Knoll

Enabled the first direct visualization of nanoscale structures, becoming a critical tool for characterizing nanomaterials [2].

1959

“There’s Plenty of Room at the Bottom” Lecture

Richard Feynman (Caltech)

Provided the visionary, theoretical foundation for nanotechnology, proposing the direct manipulation of individual atoms [2].

1974

Coining of the Term “Nano-technology”

Norio Taniguchi (Tokyo University of Science)

First use of the term to describe precision engineering and manufacturing at the nanometer scale [2].

1981

Invention of Scanning Tunneling Microscope (STM)

Gerd Binnig and Heinrich Rohrer (IBM Zurich)

Revolutionary invention that allowed for the imaging and, later, manipulation of individual atoms on a surface [2].

1985

Discovery of Fullerenes (Buckyballs)

Robert Curl, Harold Kroto, and Richard Smalley (Rice University)

Discovery of C60, a new spherical allotrope of carbon, which opened the field of fullerene chemistry and carbon nanomaterials [2].

1986

Invention of Atomic Force Microscope (AFM)

Gerd Binnig, Calvin Quate, and Christoph Gerber (IBM/Stanford)

Expanded scanning probe microscopy to non-conductive materials, including biological samples, democratizing nanoscale imaging [2].

1986

Publication of Engines of Creation

K. Eric Drexler

Popularized the concept of molecular nanotechnology, introducing ideas like assemblers and the “grey goo” scenario to the public [3].

1989

First Manipulation of Individual Atoms

Donald Eigler and Erhard Schweizer (IBM Almaden)

Used an STM to spell “IBM” with 35 xenon atoms, providing definitive proof of Feynman’s vision of atomic manipulation [2].

1991

Discovery of Carbon Nanotubes (CNTs)

Sumio Iijima (NEC Corporation)

Discovery of tubular carbon structures with extraordinary mechanical and electrical properties, becoming a cornerstone of nanotechnology [2].

2000

Launch of the National Nanotechnology Initiative (NNI)

U.S. Government

A major federal research program that coordinated and funded nanotechnology research, accelerating its development globally [2].

2004

Isolation of Graphene

Andre Geim and Konstantin Novoselov (University of Manchester)

Isolation of a single, one-atom-thick sheet of carbon, a 2D material with unprecedented properties, sparking a new wave of research [2].
