1. A microfluidic sensor, the microfluidic sensor comprising:

  • a microchannel that comprises a reaction site that comprises a reagent and a sample inlet, wherein the microchannel is configured to receive a liquid substance comprising a chemical at the sample inlet that travels by capillary action to the reaction site;

    a temperature sensor located proximal the reaction site of the microchannel and configured to measure a temperature as a result of a reaction between the reagent and the chemical in the liquid substance; and

    a controller communicatively connected to the temperature sensor, the controller receives the temperature measured by the temperature sensor and derives a concentration of the chemical in the liquid substance from the temperature.
