Tiny microbots able to automatically shift shape to travel through the body could improve targeted therapies and drug delivery.
Developed by teams at EPFL and ETH Zurich, the origami-like microbots are made up of layers of a biocompatible hydrogel embedded with magnetic nanoparticles. While the bots can be directed via an external electromagnetic field, they can also automatically shift shape when triggered by a specific environmental agent—such as changing from a flat tail for paddling to a helix shape in the presence of a high concentration of sucrose.
