Engineers have demonstrated how to make microscale origami-like containers that could be used as drug delivery devices in the body. The hinged structures were created in polysilicon and are only 30 micrometers on a side. (One inch is 25,400 micrometers.)
The team from the USC Information Sciences Institute published their “recipe” in the Journal of Micromechanics and Microengineering.
