13. Nano-Robot Swarms
Engineers have assembled nickel-coated silica nanoparticles that respond to rotating magnetic fields. These swarms can navigate fluid channels and release cargo at precise locations. Each nano-robot measures less than 200 nm, collectively acting like an adaptable micro-drug delivery system. According to ScienceDaily, researchers achieved directional control and tunable swarm shapes.
These swarms can penetrate tissue barriers and release chemotherapy agents at tumor sites, minimizing off-target toxicity. Ongoing studies aim to integrate biosensors and feedback loops for on-demand dosage, heralding personalized, precision nanomedicine.
