Researchers at UC San Diego are using state-of-the-art science to translate the hidden language of human metabolism.

In Nanotechnology and Precision Engineering, researchers developed a microrobot capable of manipulating small droplets in the presence of magnetic fields. To make their robot, they mixed neodymium magnetic particles and sugar with a chemically stable polymer. The sugar was then dissolved away, leaving holes throughout the polymer for increased surface area. Lastly, the team treated the polymer with plasma to make it attract water and other liquids. Including the magnetic particles allowed the team to control their robot by applying magnetic fields, and using powerful neodymium particles made the robot more responsive and effective compared to existing magnetic microrobots.
