How schools of 'microswimmers' can increase their cargo capacity

A new study published in Physical Review Letters describes a way to increase the cargo capacity of microscopic, self-propelled droplets known as "microswimmers." Researchers from the University of Pennsylvania and the Max Planck Institute for Dynamics and Self-Organisation found that when a school of microswimmers move in the same direction inside a narrow channel, they can increase the number of particles they can carry by 10-fold. Their findings have implications for applications ranging from ...
