Nanotechnology

We are manipulating matter: building, controlling, and applying functional systems at the nanoscale (one to 100 nanometers, or $10^{-9}$ meters).

Nanotechnology is the precise engineering of functional systems at the molecular level: the $10^{-9}$ meter scale. This is not just theory; we see major commercial impact now. Consider materials science: carbon nanotubes (CNTs) offer 100 times the tensile strength of steel at one-sixth the weight. In medicine, nanocarriers (e.g., liposomes) precisely deliver chemotherapy drugs, minimizing systemic toxicity. The technology fundamentally reshapes electronics, energy storage, and diagnostics (rapid, point-of-care sensors). It is a foundational capability driving innovation across all major industrial sectors.
