An international team of scientists, with the participation of specialists from the University of Pennsylvania, has developed microrobots for effective brushing of teeth without hands, the study was published in the journal ACS Nano.
The devices consist of iron oxide nanoparticles, which have both catalytic and magnetic activity. Using a magnetic field, researchers can direct movement and configuration to form bristle-like and filamentous structures for cleaning teeth.
In addition, microrobots also produce antimicrobials that kill harmful oral bacteria.
< p>Scientists have also conducted a number of experiments using this system on models and real human teeth. Testing has shown that the robotic nodes can take many forms, virtually eliminating the sticky biofilms that lead to cavities and gum disease.
“Proper oral care is a labor intensive process. You should brush your teeth, then floss, then rinse your mouth. This is a multi-step process. The robotic system can perform all three operations simultaneously without human assistance, it is an automated process", — explained study co-author Hyun Koo.
