Abstract

Sensors made from single carbon nanotubes have great potential to function as nanometer-scale electrical probes for single-cell studies (see image). A nanotube is used both as an amperometric and a transistor sensor and signals are correlated with the activity of a macrophage cell located on the device. In addition, the stability and sensitivity issues are highlighted and ways to enhance nanotube sensors are demonstrated.
