What is Nanotechnology with a suitable example?

Nanotechnology involves the manipulation and application of materials at the nanoscale, typically between 1 and 100 nanometers. This field enables the development of innovative products and processes in various sectors, including medicine, electronics, and materials science. A notable example is the use of nanoparticles in cancer treatment, where engineered particles can target and deliver drugs directly to tumor cells, minimizing damage to surrounding healthy tissue.
