nano
The iPod Nano hit the market a little less than 17 years ago, and the nano-bots from Big Hero 6 hit the big screen eight years ago. The word "nano" appears in pop culture every few years and always means "small". However, nanoparticles are a lot smaller than an iPod. Actual nano-bots are also much smaller. They have the potential to help our oceans and bodies, but for now, they’re just tiny robots — with huge potential.
