Nanochemistry: Exploring the Nanoworld

The Nobel Prize in Chemistry awarded nanochemistry. This field studies materials at very small scales.⁷ People have been making nanostructured materials since ancient times. For example, Rome and medieval Europe had early samples.⁷ In 1857, Michael Faraday found colloidal “ruby” gold. This showed how tiny materials can have special properties.⁷ John Bardeen, William Shockley, and Walter Brattain made the first semiconductor transistor in 1947. This led to electronic devices. It started the Information Age.⁷ Gordon Moore talked about Moore’s Law in 1965. This is the idea that the number of transistors on a chip doubles every 2 years. It shows how important nanochemistry is in electronics.

Synthesis and Characterization of Nanoparticles

⁷ Sumio Iijima found carbon nanotubes in 1991. They were very strong, conductive, and good at heat. They are used in electronics, biology, and more.⁷ Chad Mirkin invented dip-pen nanolithography® in 1999. It allows for making repetitive patterns of circuits and biomaterials.
