The brain is messy, electric, and alive—nothing like the rigid devices we try to plug into it. But nanotech might be the missing link! This week, we unravel a review that shows how nanomaterials like carbon nanotubes and smart nanoparticles could finally let machines talk to neurons in their own language. Whether it’s sensing signals or zapping cells with magnetism, nanotech is unlocking radical new ways to interface with the mind. We also touch on "brain-on-a-chip" models and ask: just because we can, should we?
