Penn researchers invent microrobots to brush teeth

Researchers at Penn, led by Michel Koo, DDS, MS, PhD, founding Director, Center for Innovation & Precision Dentistry, and Edward Steager, Research Investigator in Penn Engineering’s GRASP Lab have developed a hands-free system of shapeshifting microrobots to help automate the process of brushing and flossing teeth.

In a fascinating proof-of-concept study, a robotic microswarm of nanoparticles, arranged in bristle-like structures, effectively cleaned plaque and decay-causing bacteria from both mock and human teeth.

PCI is actively seeking potential partners and investors for further development of this exciting invention.
