In which length scale does nanotechnology operate?

Nanotechnology operates primarily at the scale of 1 to 100 nanometres. This range is crucial because it is at this scale that materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. The manipulation of matter at the nanoscale allows for innovations across various fields, including medicine, electronics, and materials science, enabling the development of new products and technologies.

At this size, nanomaterials can have increased strength, lighter weight, enhanced chemical reactivity, and improved electrical properties. For instance, nanoparticles can be used to deliver drugs more effectively within the body, or to create materials that are stronger yet lighter compared to those made from conventional materials.

Understanding this scale is essential for anyone studying or working in fields that engage with nanotechnology, as the properties and behaviors of materials can vastly change once reduced to the nanoscale.
