How does nanotechnology work?

Nanotechnology is the understanding and control of matter at the nanometer scale, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.

Nanotechnologies involve the design, characterization, production, and application of nanoscale structures, devices, and systems that produces structures, devices, and systems with at least one novel/superior characteristic or property.

At the core of nanotechnology is the fact that the properties of materials can be different at the nanoscale for two main reasons:

First, nanomaterials have a relatively larger surface area when compared to the same mass of material produced in a larger form. This can make materials more chemically reactive (in some cases materials that are inert in their larger form are reactive when produced in their nanoscale form), and affect their strength or electrical properties.

Second, so-called quantum effects can begin to dominate the behaviour of matter at the nanoscale - particularly at the lower end – affecting the optical, electrical and magnetic behavior of materials.
