Where's the nano particle? Explanation

find the particles - play

What's the puzzle?

mass of moleculesDeveloping technologies that work at the nanoscale involve manipulating particles that are more than 100,000 times smaller than a human hair. Talk about finding a needle in a haystack.

In this game you are trying to find the right nanoparticle. As the challenge gets harder and harder, imagine you are a scientist trying to trap molecules of arsenic or build a carbon nanotube wire from atoms of carbon. Play the game.
