This presentation provides an overview of nanotechnology. It begins by defining nanotechnology as the study and manipulation of matter at the atomic scale, around 1 to 100 nanometers. The history of nanotechnology is then summarized, noting Richard Feynman's 1959 concept and key developments like the scanning tunneling microscope. Tools for nanotechnology like atomic force microscopes and lithography techniques are outlined. Specific nanomaterials like carbon nanotubes, nanorods, and potential nanobots are then described briefly, noting their properties and applications in areas such as electronics, medicine, and materials science.
