摘要

Living cells can be exploited to sense and process environmental stimuli, including poorly defined microenvironments, biological markers of disease, defects in materials and complex small molecules. But obtaining a reliable signal from individual cells has proved a challenge. On page 39 of this issue, Prindle et al.1 report a solution to this problem: a sensor composed of millions of bacterial cells that communicate with each other over long distances (up to 2.4 centimetres). The cells respond to the presence of arsenic by altering the rate at which they produce synchronized pulses of fluorescence.
