The Indian Institute of Science (IISc) located in Bengaluru have
developed tiny nanobots to help with Root Canal Treatments. The
nanobots can be injected into the teeth to kill bacteria, and can
better dental treatment by killing germs deep inside dentinal
tubules, according to a release issued by the institute.
Root Canal Treatments (RCT) are a common technique which by
tooth infections are treated by removing the soft tissue that is
infected called the pulp. This is done by flushing the tooth with
antibiotics or other chemicals to kill the bacteria that has caused
Researchers at IISC have managed to create nanobots that are
made from silicon dioxide and coated with iron which can be
controlled by a device that creates a low intensity magnetic field.
This new technique and study has been published by the journal
Advanced Healthcare Materials.
The nanobots have been developed by startup Theranautilus and
the technology of the magnetic field allows for the control of the
movement of the bots. IISC has said that by manipulating the
frequency of the magnetic field, researchers were able to move
around the nanobots and get them to penetrate deep layers of the
tubules. The tweaking of the magnetic field also creates heat which
also kill bacteria nearby.
Researches in the past have also shown that such nanoparticles
can trap and move objects using light as well as swim through blood
and inside living cells which can also be used to stick strongly to
cancer cells, thereby tracking them.
CommentsAmbarish Ghosh, Professor at the Centre for Nano Science
and Engineering, who led the research said, 'These studies have
shown that they are safe to use in biological tissues. We are very
close to deploying this technology in a clinical setting, which was
considered futuristic even three years ago. It is a joy to see how
a simple scientific curiosity is shaping into a medical
intervention that can impact millions of people in India
