To understand what a nanotechnology engineer technician does, you first need to visualize just how tiny a nanometer is. A nanometer is one-billionth the size of a meter—a strand of human hair is 100,000 nanometers wide. So it's safe to say that a nanometer is really, really little. These technicians work with this measurement scale to break matter down into atoms or molecules. In doing so, they're able to help produce things like mini computer parts and items coated with layers of chemicals that have been broken down into nanoparticles. (We're talking about sunscreens, stain-resistant clothing, and antibacterial bandages, to name a few.) To succeed in this tech-driven field, which combines elements of chemistry and engineering, you should be able to dream big while also having the patience to think (very, very) small.
