Nanotechnology
Nanotechnology is the field of science and engineering focused on controlling matter at approximately the nanoscale, typically between 1 and 100 nanometers. At these dimensions, materials often exhibit size-dependent properties that differ significantly from bulk behavior.
Overview
These size-dependent characteristics arise from factors such as increased surface-area-to-volume ratios and quantum effects. For example, semiconductor nanocrystals exhibit tunable optical properties, while nanoscale carbon structures can display distinctive electrical and mechanical behaviors. Nanoscale fabrication and synthesis allow materials and devices to be structured to exploit these specific physical regimes.
Why it matters
Nanotechnology contributes to developments in targeted therapeutics, semiconductor fabrication, and high-performance functional composites. These applications rely on nanoscale structural control to modify chemical reactivity, electrical transport, and biological interactions.
