Nanotechnology: Physics at the Smallest Scales

Nanotechnology works at the nanoscale, about one-billionth of a meter.
At this size, materials gain unusual electrical, optical, and mechanical properties.
Carbon nanotubes are stronger than steel yet lighter than plastic.
Quantum dots glow in vivid colors, used in TVs and medical imaging.
Nanoparticles can deliver drugs directly to targeted cells in the body.
Nano-coatings make surfaces water-repellent, anti-scratch, or self-cleaning.
The laws of quantum physics dominate at the nanoscale.
Nanotech is revolutionizing electronics, from faster chips to flexible devices.
Solar cells enhanced with nanomaterials capture more sunlight efficiently.
Nanotechnology promises breakthroughs across medicine, energy, and materials science.
