1. A method of detecting an analyte in a fluid, comprising:

  • providing a sensor array including at least a first sensor and a second sensor in an arrangement having a defined fluid flow path;

    exposing the sensor array to a fluid including an analyte by introducing the fluid along the fluid flow path;

    measuring a response for the first sensor and the second sensor; and

    detecting the presence of the analyte in the fluid based on a spatio-temporal difference between the responses for the first and second sensors, wherein detecting the presence of the analyte includes generating a spatio-temporal response profile indicative of the presence of the analyte based on the spatio-temporal difference between the responses for the first and second sensors.
