    Study Notes

    Introduction and History of Nanobiotechnology

    • The foundation of nanotechnology was laid in December 1959 when Richard Feynman delivered a lecture titled "There's Plenty of Room at the Bottom" at the California Institute of Technology.

    • Feynman's lecture addressed the manipulation of atoms and molecules at a scale of 10^-9 meters, now known as the nanoscale.

    • The term "nanotechnology" was coined by Norio Taniguchi in 1974 to describe the precision machining of materials at the nanoscale.

    • The National Nanotechnology Initiative defines nanotechnology as the "manipulation of matter with at least one dimension sized between 1 to 100 nanometers".

    • One nanometer is equivalent to 1/25,400,000 of an inch.

    • To visualize this scale, if a marble represented one nanometer, then one meter would be the size of the Earth.

    • The discovery of the Scanning Tunneling Microscope (STM) and the Atomic Force Microscope (AFM) in the late 20th century revolutionized the advancement of nanotechnology by enabling scientists to observe and manipulate atoms.

    • Despite the relatively recent rise of nanoscience as a field of study, nanoscale materials have been used for centuries.

    • The stained glass windows of medieval churches demonstrate the use of nanoscale materials, where artists utilized silver and gold particles of varying sizes to achieve specific colors and effects.
