Detection of analytes using live cells

The present invention provides sensor cells comprising a receptor that binds to an analyte indicative of the presence of an agent, where binding of the analyte to the receptor triggers a detection event that is indicative of the presence of the agent. In certain embodiments, the detection event is appearance of a reporter detectable by the naked eye. The present invention also provides uses of such sensor cells for detecting the presence of an agent in a sample.
