Swarms of tiny 'nose robots' clear out sinuses
Many persistent sinus infections involve biofilms – colonies of bacteria that group together to resist efforts to kill them. Now, researchers have developed biofilm-blasting bots that could handily deal with these, and other, bacterial infections.
In simpler terms, the particles, which were invented by researchers at The Chinese University of Hong Kong, contain a mix of the elements bismuth, oxygen and iodine along with the addition of a single atom of copper. "This microrobot platform not only demonstrates impressive antibacterial capabilities but also presents exciting opportunities for safe and targeted treatment of other deep-seated infections," said team lead, Zhang Li. Should future testing reveal the techniques effectiveness in human patients, the microbot system could offer an alternative to treating hard-to-fight sinus infections without having to turn to system-wide treatments like antibiotics.
