Use of micropropellers for mechanical movement in stomach

Another example of using concepts from nature in science- if it ain’t broke, don’t fix it! By observing how H. pylori can move through the viscous mucous layer via use of its flagellum, these scientists created artificial glass, electromagnetic propellers that are immobilized to the bacteria via use of a protein based solution. Mechanical movement in the viscous (low Reynolds) regime is much more efficient for movement than trying to create a mucous-polymer interface. This technology would be huge in drug delivery applications for targeted therapy as the capsule could zoom to targeted regions much more effectively than binding proteins could.
