Microswimmers are small, self-propelled organisms that can move through fluids at low Reynolds numbers. They are found in a wide variety of environments, including oceans, lakes, rivers, and even the human body. Microswimmers can be used for a variety of applications, such as drug delivery, environmental remediation, and sensing.
One of the challenges in using microswimmers for these applications is their limited cargo capacity. Microswimmers are typically very small, so they can only carry a small amount of cargo. This limits their usefulness for applications that require a large amount of cargo to be transported.
There are a number of ways to increase the cargo capacity of microswimmers. One way is to use a larger microswimmer. However, this can make the microswimmer more difficult to control and maneuver. Another way to increase cargo capacity is to use a school of microswimmers.
A school of microswimmers is a group of microswimmers that move together in a coordinated fashion. This can increase the cargo capacity of the microswimmers, because the microswimmers can share the load of carrying the cargo. Additionally, a school of microswimmers can be more efficient at moving through fluids than a single microswimmer.
There are a number of ways to create a school of microswimmers. One way is to use a chemical attractant. Another way is to use a physical force, such as a magnetic field or a light beam.
Schools of microswimmers have a number of potential applications. They could be used to deliver drugs to specific parts of the body, to clean up environmental spills, or to sense chemicals in the environment.
Schools of microswimmers offer a number of advantages over single microswimmers. They can increase the cargo capacity of the microswimmers, they can be more efficient at moving through fluids, and they can be more easily controlled and maneuvered. As a result, schools of microswimmers have a number of potential applications in medicine, environmental science, and sensing.
