La nanotecnología (primera parte): ¿qué es?

Nanotechnology involves manipulating materials at the atomic and molecular scale to enhance their properties. It is already used in various products, making them smaller, stronger, and more efficient. The technology operates on a nanometer scale, where materials exhibit unique properties. For instance, nanosilver is antibacterial, and carbon nanotubes are extremely strong and light. The future of nanotechnology holds the promise of revolutionary changes, such as indestructible materials and low-cost production. However, the potential risks and ethical concerns are still under debate.
