Abstract

Systems and methods are provided for determining a presence, type, or amount of an analyte in fluid. An analyte sensor can include a substrate that includes a chiral molecule for sensing the presence of the analyte in the fluid. A property of the chiral molecule may change in response to sensing the presence of the analyte. The change in the property of the chiral molecule can cause a change in polarization of a beam of light traveling through the substrate. The presence, type, or amount of the analyte can be determined based on the change in polarization of the beam of light. The analyte sensor, along with optical fibers, can be used to determine the presence, type, or amount of an analyte in a fluid sample from a wellbore.
