Infrared navigation lets magnetic nanorobots deliver drugs with real-time precision tracking (opens in new tab)

Nanorobots have shown great promise in precision medicine over the past few decades. Yet one key challenge remains: how to track and guide these tiny devices in real time as they move through complex physiological environments. Existing imaging approaches often require long exposure times to detect ionizing radiation or suffer from blurred images because of strong light scattering in living tissues.
