It's no easy task to uncover the mysteries of the deepest parts of the human brain. But what if we could send tiny micro-nanobots into the brain to explore and map its hidden regions? This might sound like science fiction, but it's an intriguing idea that scientists are starting to take seriously. The big question, however, remains: how do we control the movement of these microscopic robots?
A research team from the National Technical University of Athens has come up with a creative solution inspired by nature. They're looking at how bats use echolocation to navigate and hunt. Last month, at the IEEE Engineering in Medicine and Biology Society conference in Orlando, Florida, they presented computer simulations showing that just four micro-robots could locate a small tumor within minutes.

Engineers around the world are working on developing various types of nanobots, especially those capable of delivering drugs inside the body. But the team led by Panagiotis Katrakazas at the National Technical University of Athens has a different focus. They're interested in using nanobots to detect hard-to-find brain lesions deep within the brain.
Katrakazas explained, "The main idea is to inject nanobots into the body, let them move through the brain, identify where the damage is, and then use drugs or surgery to treat it." The team is currently studying how crawling nanobots interact with neurons along their path. By "pinching" the neurons, the nanobots can determine if they're healthy — healthy ones emit electrical signals, while damaged ones don't.
But the biggest challenge is getting the nanobots to work together as a coordinated team. To solve this, Katrakazas' team developed an algorithm inspired by bat behavior. This algorithm, originally based on how bats use sound signals for navigation and hunting, was adapted to simulate the way bats send acoustic signals. They applied this to a device similar to an EEG scanner, which sends sound waves into the brain.
The team hopes to use this technique to guide the nanobots through the brain. While the method has been tested in simulations, there's still a long road ahead before such "bat-like" nanobots can be tested in humans.
Roderich Gross from the University of Sheffield in the UK points out that one of the first challenges is understanding which technology will allow these tiny robots to both sense and emit sound signals.
Despite the hurdles, Katrakazas remains optimistic. She believes that within a few years, a system like this could be tested in human trials. "Some doctors have already shown interest," she said. Whether this vision becomes reality remains to be seen, but the idea of using nature-inspired technology to explore the brain is opening new doors in medical science.
