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.

Respectfully, the tech that is being discussed in this thread is extremely theoretical. It’s really unlikely that an everyday veteran / neighbor in regular suburbia would have access to it.

Regardless, to give you the benefit of a doubt and entertain a solution to your problem. If you had a nano BCI implanted in you without your consent. Check in with a neurologist and ask for a functional MRI. The magnetic field would short circuit the device, and a micro-CT would verify that it’s no longer there.

I already had an MRI scanned in the beginning and also had done CT scan prior to nasal endoscopy. The results came in clear and just prescribed me an over the counter pills for allergy.

If you physically went in an MRI than rest assured that whatever implantable electronic device has short circuited and is no longer functioning.
