Researchers have found that nerve cells, carried by magnetically powered nanorobots, can be guided towards specific sites in brain tissue to then establish structural and functional connections with the nerve cells of that tissue. While not yet realised in living organisms, the researchers believe their nanorobotic system could potentially be used in patients to treat nerve-related degenerative diseases and injuries.
They describe their findings in the journal Advanced Materials (“A Neurospheroid-Based Microrobot for Targeted Neural Connections in a Hippocampal Slice”).
In the study, a magnetic neurospheroid (Mag-Neurobot), which is made up of magnetic nanorobots carrying live nerve cells (neurons), was introduced into a slice of brain tissue and then magnetically guided to a precise location within that tissue using an external magnetic field.
