Nanoscale ‘stealth’ probe

Abstract:
Engineers at Stanford have created a nanoscale probe they can implant in a cell wall without damaging the wall. [Almquist and Melosh, PNAS (2010) 107, 5815.]
A nanometer-scale probe designed to slip into a cell wall and fuse with it could offer researchers a portal for extended eavesdropping on the inner electrical activity of individual cells.

Everything from signals generated as cells communicate with each other to "digestive rumblings" as cells react to medication could be monitored for up to a week, say the Stanford engineers.
