Nanotechnology is moving from fiction to reality, with at least two universities studying the use of miniature robots inside the body to treat diseases and address other health concerns.

Fans of Fantastic Voyage take heart: The innovative nanotechnology featured in the 1966 movie about miniaturized doctors entering a human body may actually be coming true—sort of.

Researchers at both Stanford University and Purdue University have recently published studies on the use of miniaturized robots inserted into the body to treat certain health concerns. The robots could be used to delivered timed doses of medicine, chart the course of a tumor or disease, or even remove obstructions such as blood clots.

While nanotechnology has long been a popular topic in fiction, from Michael Crichton’s 2003 novel Prey to the most recent James Bond movie No Time to Die, it’s starting to show up in the real world. Several programs over the past few years have focused on the development of pills fitted with digital health sensors that are ingested and used to deliver timed doses of medicine and/or track vital signs and medication results, though the digital health company best known for developing that technology, Proteus, filed for bankruptcy in 2020.

Now some researchers are trying a new delivery method.

At Purdue, “microbots” developed by Hyowon “Hugh” Lee, an associate professor from the Weldon School of Biomedical Engineering, have been used to remove blood accumulating around the brain after a stroke. Working with neurosurgeons Timothy Bentley, MD, of Purdue’s College of Veterinary Medicine, and Albert Lee, MD, from Goodman Campbell Brain and Spine in Carmel, Indiana, he successfully removed pooled blood in six of seven animals.
