Nanotechnology is unique, because it is (blank) enough to show quantum mechanical features but still large enough to be controlled and manipulated.

Explanation:

Nanotechnology is the technology that is responsible for the manipulation of matter on a nanometric scale (). In addition, it works with the design at the atomic or molecular level.

This technology is based on nanoscience that is responsible for modifying or adulterating matter as it exists, but unlike common sciences, it does so at a molecular level, that is, on a very small scale. Thanks to this, it is possible to manufacture materials and machines from the rearrangement of atoms and molecules with various purposes, mainly industrial and medical.

Therefore:

Nanotechnology is unique, because it is small enough to show quantum mechanical features but still large enough to be controlled and manipulated.
