Swarms of tiny nose robots could clear infected sinuses, researchers say

Chinese and Hong Kong scientists succeed in animal trials, but potential problems include risk of devices being left in body and public suspicions

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.
