What is a nanostructure?

A nanostructure is a material or object with at least one dimension measuring between 1 and 100 nanometers (nm), which is typically on the scale of atoms and molecules. These structures exhibit unique physical and chemical properties due to their small size and high surface area-to-volume ratio. Nanostructures are widely used in various fields, including Nanotechnology, materials science, and medicine, enabling innovations such as drug delivery systems, improved catalysts, and advanced electronic devices. Their behavior often differs significantly from bulk materials, leading to new applications and functionalities.
