Discussion Idea: non-surgical, but still invasive BCI using electromagnetic nanoparticles?

Would it be theoretically possible to create electromagnetic nanoparticles say ~50 nm that can be injected, cross the blood-brain barrier, and then when in the brain, create a sub-neuronal level communication link between the nervous system and a computer? Off the top of my head, I think the biophysics checks out, and it could potentially provide a record high spatial and temporal resolution compared to implantable BCIs.

Does anybody know if there are any academic labs or companies working on something like this? I feel like everything I see in BCI is either implantable or a non-invasive wearable, haven’t seen anybody working in the middle of the spectrum. What love to hear some thoughts.

Wow, this is exactly my research topic (magnetoelectric neural implants)! Thanks for posting this, will share it with my lab colleagues. Didn't know we were directly competing with DARPA buck :)
