An IIT Kharagpur alumnus may have revolutionised root canal with nano robots

An Indian Institute of Science (IISc)-incubated start-up and a group of researchers at the premier academic institute in Bengaluru have developed nano-sized bots that can kill bacteria deep inside dentinal tubules boosting root canal treatments.

The group of researchers at the IISc and Theranautilus, a start-up led by Ambarish Ghosh, professor at Centre for Nano Science and Engineering (CeNSE) and an IIT Kharagpur alumnus, has shown that nano-sized robots controlled by a magnetic field can boost the success of root canal treatments by killing bacteria inside microscopic canals in the teeth, known as dentinal tubules.
