Researchers at Penn State demonstrate the first steps in the design of tiny particles that can perform specialized tasks, such as targeted delivery of drugs or other cargo.
A group of tiny particles followed "breadcrumbs" left behind by a different group of particles in new experiments demonstrating the first steps in creating intelligent communicating systems involving active particles—sometimes called nanobots—that perform specialized tasks.
The experiment was possible thanks to a new microfluidic tool developed by researchers at Penn State that allowed them to observe the particles for far longer than had been previously possible.
The extended time allowed the team to watch as one group of particles followed a chemical gradient while creating a different chemical gradient in its wake, which was followed by the second group of particles.
