Using tiny robots to deliver drugs is promising pathway when it comes to limiting side effects and increasing effectiveness, and some take a more theatrical approach than others. Scientists at Purdue University have come to the party with a back-flipping microbot that can tumble its way through the colon to release its payload when desired, all while being controlled externally by a magnetic field.

Back in July 2018, researchers at Purdue University created the world’s fastest-spinning object, which whipped around at 60 billion rpm – and now that seems like the teacup ride at Disneyland. The same team has now broken its own record using the same technique, creating a new nano-scale rotor that spins five times faster. read more
