Nanotechnology
Nanotechnology is the multidisciplinary field of science and engineering concerned with designing, synthesizing, and applying materials and devices at the nanoscale — structures between 1 and 100 nanometers — where quantum mechanical effects become dominant and matter exhibits fundamentally different properties than in bulk form.
Overview
These scale-dependent phenomena are the foundation of nanotechnology's power: gold nanoparticles absorb light at different wavelengths depending on their size; carbon nanotubes display electrical conductivity and tensile strength far exceeding conventional materials; and quantum dots — semiconductor nanocrystals tunable by size — have transformed display technology and biomedical imaging. Nanoscale engineering does not simply miniaturize existing technology but creates entirely new functional regimes engineered from the ground up.
Why it matters
Nanotechnology has enabled breakthrough advances across medicine, enabling precision drug delivery systems that minimize side effects by targeting specific cells, and across materials science and electronics, where nanoscale structures now underpin semiconductor devices, high-performance composites, and next-generation energy storage technologies.
