Nanoscale 'stealth' probe slides into cell walls seamlessly, say engineers

Engineers have created a nanoscale probe they can implant in a cell wall without damaging the wall. The probe could allow researchers to listen in on electrical signals within the cell. That could lead to a better understanding of how cells communicate or how a cell responds to medication. The probe could also provide a better way of attaching neural prosthetics and with modification, might be an avenue for inserting medication inside a cell.
