Which term refers to materials specifically designed to operate at the nanoscale?

The term that refers to materials specifically designed to operate at the nanoscale is nanoscale materials. At this scale, typically between 1 and 100 nanometers, materials exhibit unique properties and behaviors that differ from their larger-scale counterparts. These unique characteristics arise from the increased surface area to volume ratio and quantum effects, which can significantly alter the electrical, optical, and mechanical properties of the materials.

Nanoscale materials have applications across various fields, including medicine, electronics, and materials science, where their enhanced properties can be utilized for innovative solutions. In contrast, microscale materials refer to larger dimensions that do not capture the unique phenomena associated with nanoscale engineering and materials, while standard and bulk materials generally refer to those used at macro or everyday scales without the specialized properties attributed to nanoscale materials.
