Confirming Purcell’s Scallop theorem, the nanobot did not move ... they hope it will aid future researchers in designing nanobots that can swim through blood vessels and body fluids.

the scallops we eat and love are bivalve mollusks, and are actually adductor muscles, joining together both halves of the sea creatures' shells and allowing them to literally swim underwater.
