What is the definition of nanotechnology?

Nanotechnology is defined as the manipulation and engineering of materials at the nanoscale, typically around 1 to 100 nanometers. This scale is critical because it is where quantum mechanical effects become significant and materials often exhibit unique physical and chemical properties that differ from their bulk counterparts.

By working at this small scale, scientists and engineers can create new materials and devices with enhanced functionalities, such as increased strength, lighter weight, or improved conductivity. This can lead to advancements in various fields, including medicine, electronics, and energy production.

The focus on nanoscale manipulation is what distinguishes nanotechnology from other fields, emphasizing the innovative techniques and applications that arise when working at these incredibly tiny dimensions.
