Microrrobots: for Your Mouth

What’s New?

Dental cleanings will never be the same. CARs are microrobots specifically designed to remove bacterial plaque from hard-to-reach areas. They can also clean the insides of catheters, implants, pipes, or any surface where bacterial plaque grows. This is a great advance for the post-antibiotic age.

How Do They Do It?

With catalytic abilities and iron oxide particles driven by magnetic fields, CARs kill bacteria, break up the surrounding protection matrix, and remove the biodegraded remains with high precision.

Who invented them?

A multidisciplinary group made up of biologists, engineers, and dentists from the University of Pennsylvania. The study was led by Hyun Koo from the School of Dental Medicine and Edward Steager from the School of Engineering and Applied Science. It was recently published in the scientific journal Science Robotics.
