The American Chemical Society (ACS) has produced a short (4’45”) video about nanobots. Most people are familiar with nanobots as they have been featured many times in science fiction disaster scenarios. At this point, scientists appear to be rebranding nanobots as either nanorobots or molecular machines or nanomachines.  Here’s more from an Oct. 12, 2015 ACS news release on EurekAlert,

Nanomachines – including nano-sized motors, rockets and even cars – are many orders of magnitude smaller than a human cell, but they have huge promise. In the future, they could deliver drugs anywhere in the body, clean up oil spills and might even be used as artificial muscle cells. Find out more about these molecular machines (and the challenges that nanobot researchers still face) in Reactions’ latest video, produced in collaboration with the University of Nebraska’s SciPop series: https://youtu.be/loaqIqKCmog.

I’ve embedded the video here,

I quite enjoyed the archival footage they included here along with the inventory of nanobots.
