Understanding Nanotechnology

Nanotechnology involves the manipulation of matter on a nanoscale, typically measured in units of nanometers (nm), where 1 nm is equivalent to one-billionth of a meter. To put this into perspective, a human hair is approximately 80,000 nm thick. At this scale, the principles of classical physics give way to the strange and fascinating realm of quantum mechanics.

Nanoscale Materials and Properties

When materials are shrunk to the nanoscale, their physical and chemical properties undergo significant changes. For instance, nanoparticles can exhibit unique optical, electrical, and magnetic properties, making them ideal for applications such as biomedical imaging, energy storage, and catalysis.
