Tiny scallop-shaped robots inside our body Tiny scallop-shaped robots inside our body

A team led by Prof. Peer Fischer from the Max Planck Institute for Intelligent Systems in Stuttgart, Germany has developed an artificial micro-swimmer, called micro-scallop, which can swim through viscous fluids by opening and closing its shells at different rates.

For many years scientists have been trying to develop microscopic robots that can swim through our body fluids and repair damaged cells or deliver medicine. Recently, scientists from the Max Planck Institute for Intelligent Systems in Germany believe they've got the perfect design. Scallops shaped robots, so small, they can barely be seen by the naked eye. These micro-robo-scallops move back and forth to swim through blood, eyeball fluids and other liquids inside our body. The scientists believe mimicking the way a true scallop swims is ideal, due to a number of reasons.

First, moving backward and forward is the best way to swim through non-Newtonian fluids, or liquids that can grow thicker or thinner, depending on the situation. As you've likely guessed, our bodily fluids are good examples (so is oobleck, or the 1:1.5-2 mixture of water and cornstarch -- seriously, try it out for yourself), as opposed to water, which can retain its viscosity. Second, the micro-scallops don't need much power be able to move that way. They don't require batteries or even motors -- just the energy provided by an external magnetic field.

According to the scientists, they don't have a particular purpose in mind for their minuscule scallop. Instead, they're hoping it becomes a reference design for other teams and companies that want to develop advanced medical technologies. If you're willing to follow these robots' example and swim through some scientific terminology, head over to Nature where the team's paper was recently published.

(a) Schematic drawing of the micro-scallop from top view. The green shapes illustrate the opening and closing shape change of the micro-scallop when actuated by an external magnetic field. The shape is a function of the magnetic force aligning the magnetic axes of the two permanent micromagnets and a restoring force because of the induced stress in the PDMS structure. The angle between the two shells α can therefore be controlled by the magnitude of the external field.
(b) Top view (microscope image) of the micro-scallop under ultraviolet illumination. The positions of the micromagnets are illustrated by white dashed circles. Scale bar, 200 μm.
(c) Time-asymmetric actuation of the micro-scallop. The slow opening and the fast closing cycles are controlled by the external magnetic field, which is generated by an exponentially decaying current (inset). Corresponding images of the micro-scallop during the opening and closing cycles are shown.
