摘要：

We present a process for fabricating a nanoscale probing device for in vitro sensing of neural activity. Single vertical platinum (Pt) nanowires were fabricated on a microelectrode array by focused ion beam (FIB) - chemical vapor deposition (CVD) in order to improve the spatial resolution of recording and to minimize damage to the cells. Electrodes in contact with cells detected prominent spontaneous electrical activity. Such small geometry of vertical nanowires may enable probing multiple sites within a cell.
