Tiny robots could clear sinus infections without antibiotics soon

Researchers have developed tiny light-activated robots to combat bacterial sinus infections. A Hong Kong-China team has effectively introduced microrobots into animal sinuses in preclinical studies to combat bacterial infections. Known as CBMRs (copper single-atom-loaded bismuth oxoiodide photocatalytic microrobots), these robots are as small as a dust speck.

They are injected into sinuses and can be guided magnetically to infection sites.

These robots work by exerting mechanical forces to break apart bacterial biofilms and generating antibacterial reactive oxygen species. In preclinical trials, they effectively cleared infections in animal models without tissue damage, showcasing non-invasive treatment potential. The researchers stated, “Our proposed microrobotic therapeutic platform offers the advantages of noninvasiveness, minimal resistance, and drug-free intervention.”
