Swarms of tiny nose robots could clear infected sinuses, researchers say. The micro-robots are a fraction of the width of a human hair and have been inserted successfully into animal sinuses in pre-clinical trials by researchers at universities in China and Hong Kong.

Swarms of tiny robots, each no larger than a speck of dust, could be deployed to cure stubborn infected sinuses before being blown out through the nose into a tissue, researchers have claimed.

The micro-robots are a fraction of the width of a human hair and have been inserted successfully into animal sinuses in pre-clinical trials by researchers at universities in China and Hong Kong.

Swarms are injected into the sinus cavity via a duct threaded through the nostril and guided to their target by electromagnetism, where they can be made to heat up and catalyse chemical reactions to wipe out bacterial infections. There are hopes the precisely targeted technology could eventually reduce reliance on antibiotics and other generalised medicines.

The tiny devices are part of the expanding field of micro- and nano-robots for use in medicine. They have also been developed to deliver drugs and to remove bacteria from medical implants such as stents and hernia meshes.

Experts believe they could be in clinical use for treating infections in bladders, intestines and sinuses in five to 10 years. Scientists in China, Switzerland, the US and the UK are developing more sophisticated versions capable of moving through the bloodstream.

Great, now something new to worry about! Mini nose robots! 🤣

“Bro what could be worse than microplastics?”
